After seeing his side suffer a 4-0 thrashing in the Merseyside derby, Roberto Martinez must somehow lift his Everton players for Saturdays FA Cup semi-final against Manchester United. But problems are mounting up for the Spaniard and preparation time for the Wembley showpiece is limited.From injuries and bans to poor form and pressure, we take a look at the challenge Martinez and Everton are facing... Merseyside derby talking points We analyse Liverpools 4-0 win over Everton at Anfield Selection dilemmaAfter resting players against Southampton last weekend, Martinez made six changes to his first team for the trip to Anfield, in a desperate bid to grab a confidence-boosting result. However, the move spectacularly back-fired, with Everton crushed by their rivals and now set to be without several key first-team players for Saturdays semi-final.Gareth Barry was forced out at half-time with a groin problem and Martinez says the midfielder is very doubtful to face Manchester United. Ramiro Funes Mori will also be missing through suspension, following his straight red card for an ugly challenge on Divock Origi. Ramiro Funes Mori will miss the FA Cup semi-final through suspension There are question marks, too, over the health of John Stones, who was substituted in the second half with stomach cramps, and fellow defenders Phil Jagielka and Seamus Coleman, who both missed the derby with hamstring problems.With Funes Mori, Stones, Jagielka and Coleman out, Martinez would be left with only Leighton Baines available from his regular senior defenders. Defensive problems Former Everton manager David Moyes said his old side were terrible in their 4-0 defeat to Liverpool Even if the likes of Stones and Jagielka pull through to play on Saturday, Martinez still has serious defensive issues to address.Evertons poor defending at Goodison Park this season has been well documented - only Aston Villa have conceded more at home - but Liverpool exposed them regularly at Anfield, too.Midfielders Muhamed Besic and James McCarthy were forced to fill in at centre-back during the second half, but even when Stones and Funes Mori were on the field, Everton conceded two poor goals which Martinez put down to an inability to do the basics right.Across the pitch, Everton were poor when they didnt have the ball. I said at half-time Everton were embarrassing, and they were, Sky Sports pundit Jamie Carragher said after the final whistle. Ive never known a derby game where it was so easy to pass the ball. When you play derby games, the pitches seem really tight whether that be at Anfield or Goodison, but it was so easy for Liverpool. Jamie Carragher says talk of the current Everton side being the best since the mid 80s is way off the mark Goal droughtWhile the focus has been on Evertons poor defending in recent weeks, at the other end, the goals have dried up. Martinezs side have scored just twice in their past six games - those goals coming from centre-back Funes Mori and central midfielder McCarthy.Top scorer Romelu Lukaku hasnt scored in five and against Liverpool, Everton failed to register a single shot on target.On Saturday, Everton come up against a Manchester United side which has kept 24 clean sheets across all competitions this season. The Toffees must re-find their goal-scoring touch at Wembley. Roberto Martinez told Sky Sports he will not have to motivate his team for Saturdays FA Cup semi-final with Manchester United Manchester Uniteds formWhile Everton suffered at Anfield, United cruised to a comfortable 2-0 home win over Crystal Palace on Wednesday night. It was Uniteds fifth win in their last six outings - only title-chasing Tottenham have beaten them in that run - and the victory saw them close the gap on the Premier Leagues top four.As well as better recent form, United have also done the double over Everton this season, sealing a comprehensive 3-0 win at Goodison Park in the first part of the campaign before winning 1-0 at Old Trafford earlier this month.Martinez and Everton must find a way to reverse their recent fortunes against Louis van Gaals men if they are to keep their season alive.Season depends on it Everton have failed to win their last six matches Indeed, Evertons season - and seemingly Martinezs tenure as manager - depends on Saturdays result.In the Premier League, the Toffees are closer to the relegation zone in points than seventh and could easily finish as low as 16th - theyre just two points ahead of fifth-bottom Crystal Palace.While the cups have offered solace this term - Everton also reached the semi-finals of the Capital One Cup - the enormity of this weekends Wembley showdown isnt lost on Martinez. Martinez: Defeat horrible Roberto Martinez embarrassed by horrible Everton defeat in derby When asked about his future as Everton boss after Wednesdays defeat, Martinez said: Its not about my job. All I want is to bring success to Everton and its about the players wanting to be themselves, coping with the occasion.We know were one step away from the (FA Cup) final and thats the only thing that can bring satisfaction to our fans. Thats the only thing were going to concentrate on.To do that, Everton and Martinez will have to overcome substantial obstacles.

Edmonton picked up its first home victory since beating Montreal on Oct. 27 and avoided matching a club-record nine-game home skid set from Oct. 16-Nov. 24, 1993. The Oilers stopped their overall 0-7-4 skid two losses shy of tying the clubs 13-game losing streak, which was set from Dec. 31, 2009-Jan. 30, 2010. The recent win over the Sharks also marked Edmontons first victory of the season against a Western Conference opponent. The Oilers are now 1-12-4 within the conference.

That win over the Rangers was Edmontons last before ending its lengthy slide against the Sharks. Edmonton beat the Sharks for just the second time in 10 meetings on Saturday, as David Perron scored the deciding goal in the third period of the 2-1 win at Rexall Place. Perron beat Alex Stalock with a wrist shot from the right circle to give Edmonton a 2-1 edge with 9:34 remaining in regulation. The shot deflected off San Jose defenseman Brenden Dillon and into the nnet for Perrons fourth goal of the season.dddddddddddd Nail Yakupov also tallied a power-play goal in the second period for the Oilers and Ben Scrivens turned aside 20-of-21 shots for the win. This doesnt mean a lot if were not going to stick to it, said Scrivens. We have to replicate that kind of effort night after night. Scrivens could get the call again tonight after beating the Sharks for the first time in his career. He is 1-2-1 with a 2.96 goals against average in four lifetime appearances against San Jose. After completing this set against the Sharks, Edmonton will begin another home-and-home series tomorrow night when it visits Anaheim. The Ducks and Oilers will then meet at Rexall Place on Friday. Tye McGinn provided San Joses lone goal on Saturday, as the Sharks had a four-game winning streak snapped. Patrick Marleau assisted on the goal to extend his point streak to five games. Stalock made 22 saves in the loss. It was his first outing since suffering a knee injury on Nov. 8 He was sharp, he made some real good saves in the first period when we needed him, Sharks coach Todd McLellan said of Stalock. He gave us a chance to get to the [intermission] and regroup. He looked comfortable and didnt fatigue at all. There were a lot of positives in his game. Antti Niemi is expected to be back between the pipes for the Sharks tonight. He is 9-1-1 with a 2.40 GAA in 11 lifetime games against the Oilers. San Jose is 7-4-2 as the host this season and is beginning a five-game homestand tonight. Edmonton has lost three straight and eight of its last 10 at the Shark Tank. ' ' '
