Manchester United take on Liverpool at Old Trafford on Sunday in a tie that could prove beneficial for both sides concerned. If the Red Devils win, they will assert their place and consolidate the fourth position in the league table, and if Liverpool get a point or three, they will again go back to the top of the tree.

United have won seven of their last nine home games against the team from Merseyside, and that will definitely boost Ole Gunnar Solskjaer. Although Liverpool won the reverse fixture in December, which eventually turned out to be Jose Mourinho's last game in charge for the Red Devils, United's current form and the fact that they are at home will mean that they will be the favourites.

As Old Trafford and the fans get ready to welcome their most famous rivals from Merseyside into Manchester, we have a look at three key battles that will shape Sunday's bout between two British and European heavyweights.
