I think in the Premier League Postecoglou required an assistant who is very good with tactics etc, The start of the tenure was good but massively helped by Vicario making astounding saves in certain matches to ensure our attacking play wasn't negated. Overall 5th is good for a first season and the club didn't get anyone, not even Solanke level that could have been some sort of replacement for Kane, even if levels below.
Season two we kept getting beat, lots of injuries, no change to the approach though, so when the players keep piling forward but end up losing match after match, they looked lost.
I said it before and I stick by it, the team needed to change it's approach in the Premier League like it did in the Europa League, we were never going to have a good season with all the injuries, but by maintaining the same tactics Postecoglou was writing his own dismissal letter. There's no need to keep attacking when the team is so depleted, the supporters will understand, we don't want to see the team lose match after match, when with a depleted team we could have dug in, a bit like Tamworth did against us in the cup for 90 minutes, eked out a a few more wins or draws.
We were like a boxer on the ropes, and instead of covering up, we're trying to throw haymakers and getting torn to pieces.
Now I'm going to be in trouble with the Postecoglou fan club again.
