I think the discussion should shift on to who should be the assistant manager. We have LSL, who although his tenure was awful as our manager, he has been the No2 for great managers like Benetez, Big Sam and even Sven with England. We have a coach with all that experience on our books and we are paying him to babysit the kids!
I think one of the real major problems with the current set up is LL and the other coaches are failing on the training pitch as this is evident in the performances on the pitch on match day. This was a similar situation to what we had under Coyle. A figure-head who wants to play football the right way and a failing backroom team. IMO the club should do exactly the same as they did with Coyle and let DF know that we need to have a shift around with the coaching set up and look to promote our own coaches like Dave Lee, Tony Kelly and especially LSL to prominent roles within the first team set up. Tottenham have done exactly this and they are currently holding their own in the Premier League - what experience did they have before? None. They were looking after the U21s.
A bigger question to ask is what precedence does a manager like DF have for dictating how our club coaches our players. You would answer as he is the manager, but his chosen team are failing in every way, so that decision should be taken out of his hands like the club did with Coyle.
I only think getting rid of DF will work because we'll be changing the coaching set up. What I'm trying to get at is, we could replace DF with Jimmy Philips, but if you kept LL and the other coaches, JP will be just as crap as DF because its the coaches that are really failing. We could theoretically change the coaching set up and keep DF in charge which could see a change on the training pitch and this could transpose to the pitch on match day.
