United are in the semi-finals of the FA Cup, while Chelsea are in the Premier League. Arsenal will play Manchester City in the other semi-final.
Manchester United have been drawn against Chelsea, who they have faced before in the competition. They have won both matches, with their most recent victory coming back in October last year. Jose Mourinho’s side are likely to be a difficult opponent for United, and it will be interesting to see how Louis van Gaal’s side match up against them.
Arsenal will face Manchester City in the other semi-final. Arsene Wenger has had a mixed season so far and it is unclear as to how his side will perform against Pep Guardiola’s side. However, City have struggled recently and could easily meet Arsenal at home and knock them out of the tournament.
