I think the energy levels were amazing considering they have only been training with him since Monday. I thought they might fade towards the end of the match.
Dyche said he's only interested in signing players (on frees) who can add something to the squad. Said as much that there is a reason they are where they are.
Take this game for what it is, first under a new manager and coaching staff and against the league leaders. new manager bounce and from his press conference it seems he's trying to instill confidence which has been sorely lacking. Whatever the result he will gain a lot from this game.
I think in our current predicament Dyche is the most pragmatic manager for the job. I guess, coming in that late, he knew we wouldn't have any/credible signings and is prepared to work with existing squad.
