Drawing Man City in the semi finals may be our best chance of beating them and ultimately give us our best opportunity of winning the FA Cup. When the semi finals are played City will still be competing in three competitions with a difficult CL fixture away at Spurs in the week following. They may well rotate players and priorities the CL over the FA Cup. However, if we were to meet them in the final they would have completed the PL and know if they were through to the final of the CL. Even if City were in the CL final there is a two week break between the two matches so no need to rest or priorities players.
