Everton could have a problem at left-back against West Ham, with Leighton Baines set to see a specialist about pain in his ankle, while Bryan Oviedo is being assessed after a knock.

Roberto Martinez still expects Baines to be available for Saturday's Premier League visit of the Hammers to Goodison Park, but the England defender hasn't started a game since the end of January.

The Toffees are targeting back-to-back league wins for just the second time this season, having seen off Aston Villa in midweek.

West Ham, meanwhile, have won both their games this week by 1-0, with Michail Antonio netting both winners, and could go as high as fourth in the table if results go their way this weekend.

Team news

Oviedo is being assessed after sustaining a knock in Tuesday's 3-1 win at Aston Villa, and he could be replaced at left-back by Baines despite his own injury problem.

Midfielder Tom Cleverley, who missed that match due to illness, will also be assessed ahead of the game, while Muhamed Besic and Darron Gibson could make their returns to action.

West Ham defender James Collins is set to miss the next three matches with a hamstring problem, starting with Saturday. Collins underwent a scan on the injury sustained in the 1-0 victory over Tottenham on Wednesday and while the results have yet to be confirmed, he is unlikely to appear again until after the next international break.

Apart from Collins, all the players present in the squad for Spurs will be travelling to Goodison with Victor Moses, Winston Reid (hamstring), Joey O'Brien (hamstring), James Tomkins (calf), Enner Valencia (ankle) and Sam Bryam (suspended) still out.

Merson's prediction

West Ham have now put themselves in with a shout of the top four. Two weeks ago you would have been thinking that West Ham and Everton have both got the FA Cup to play for, which would have made this game at Goodison Park a 'make sure no one gets injured' job.

But now West Ham have got a chance of getting in the top four, and so this has become a massive game for them. Everton have got Chelsea in the cup next weekend, but I think they are are a good team and at home they can beat anybody, even a strong side going well like West Ham.

Paul predicts: 2-1 (Sky Bet Odds 7/1)
