That was abysmal. Playing Lennon to help Kenny out is not the way to get us forward.
Knocking long balls to Rooney or Balls over the top to Rooney or balls down the channels to Rooney isn't going to work, but the defence has no option as the 3 central midfielders are so deep it's not worth giving them the ball as none of them can beat a man.
He probably won't, as Koeman was criticised for making HT changes, as it was seen as an admission he'd got it wrong, but he needs to go 4-2-3-1 lose one of the holding midfielders and get another attacker up, either DCL with Rooney in the centre of the three or DCL and Sigurdsson for Rooney and one of the central midfielders.
