For the most part I agree with you GM. I don't see us replacing Gus now. It's too late and there's no one of real calibre out there.
Where I disagree is about losing 2-0 at Utd, inasmuch as the manner of the loss. I'd have no issue with a lower-level team that went to any of the top 5 or 6 teams and lost 2-0 if they at least tried to make a game of it, and went with the intention of at least trying to get a hard-fought win or well-deserved draw. We did neither.
To be fair, the first half wasn't too bad, but the second half was a gutless and clueless demonstration of football from a very very poor team.
Personally I think if you go down 1-0 in the second half at one of the top 4, the confidence they get from that first goal means you know they're gonna throw everything at you. At that point you must change the game plan and just go for it! Not keep playing it slowly from the back and meekly takingit up the jacksy!
