I personally think too many fans are hung up on the team he took away to Moscow, his mistakes in that tournament came earlier (as far as I'm concerned).
A weak team in the group vs Hamburg and zilina meant we got a tougher draw than we should have, and even then picking a weakened team at home to cska and only getting a draw meant we were on a hiding to nothing going away. Away on an artificial pitch in the middle of winter in one of the coldest cities in europe and needing to score at least once was a big ask.
If we'd beaten Stoke at the weekend it'd have been the correct decision. I personally think the biggest problem with the selection was that it turned the fans against him, which was very noticeable in the next few games.
