Both Manchester United and Everton failed to win on Saturday, with United again drawing a blank against West Brom and the Toffees again falling to local rivals Liverpool. The two teams need to win this one at Old Trafford on Tuesday, and here's three battles that could go a long way to deciding how the game pans out...

Manchester United's difference-maker is back from suspension, finally, and he'll go straight back into the fold for the hosts. Lord, do they need him.
United are lacking a cutting edge and deadly finisher up top, and for the rest of the season at least, the Swede will need to continue being that man. Ashley Williams, and the rest of the Toffees' back three, however, are going to be doing their best to stop him.
Williams will go toe to toe with Zlatan in terms of physicality, and the whole Everton backline will be determined to perform better than they did on Saturday.
United are hopeful that Paul Pogba will return to the fold in this one, but with or without him, Henrikh Mkhitaryan will be tasked with being United's chief creator - likely through the middle.
If that does happen, Idrissa Gueye will be one of the men tasked with stopping him and stopping the hosts' momentum. Gueye averages 4.5 tackles a game - more than anybody else in the Premier League - and will be a crucial part of Ronald Koeman's plans.
Everton will likely soak up the pressure all through the evening and try and hurt United with the weapon(s) they have in the front line...
United will have a much bigger threat to worry about going backwards on Tuesday night than they did on Saturday afternoon, in the shape of Premier League top scorer Romelu Lukaku.
Lukaku, as you may know, is a rather physical being, and he'll look to stretch United by threatening in behind. Former Villarreal man Eric Bailly will be more than up for the challenge of stopping him, and this one will be one of the more interesting battles of the night.
If United are to actually win at Old Trafford, Bailly will need to be on the top of his game.
