Because it meant we were playing with 5 in midfield rather than the 3 we had played for the 1st hour. We had no width in our midfield, leaving the full backs 1 on 1 with their wingers. Clyne had it easy as Routledge was poor. Davis wasn't playing in front of Fox, he was playing in a far narrower 3. JWP was sent on to play there. Dyer was not half as effective after that.
The fact that the team as a whole couldn't keep the ball after we went 1 up, meant that Swansea could keep switching it wide. I felt MP could have made the switch at half-time, but he had faith that our midfield could have regained the upper hand. They didn't, but luckily we didn't concede.
Miss the game then did you?
