IMO, we would need to be careful about going for proper football too fast. It needs phasing out rather than a radical change. And in this league, there is a need to mix it sometimes - look at Donny who pass all the time. Yeah it looks nice but it hasn't done them much good in terms of the league table has it? (I realise they're overachieving for them BUT in terms of the overall picture, they're in mid-table and going neither up nor down.)
Just because we want to play football does not mean we'd need to get rid of anybody who couldn't ... Henderson would still have a massive role to play. He often looks frustrated by the fact the ball is round his head all the time. Utilise his strength play in different ways and he could be a very useful player.
As for Monty. I'd keep him too. We know his limitations but he does what he does better than anybody else. At times in a season, we need a player like Monty and IF we went up in this new regime of super-football, we'd need Monty in the Premier League. Monty is one of those players: solid Championship player; excellent Premier League player (relative to us of course). Look at how important he was to us in the PL.
For me:
I'd get shut of Kenny but that's a personal opinion. We need a big tall commanding keeper to get out of this division and then worry about a better shot stopper if we get out. Aksalu seems to be doing OK and impressing so we might go with him or find another. I wouldn't go with either Kenny or Bennett.
Defensively, I'd keep Morgan and I'd bring Seip in. If we could get Bartley in on loan for a season, that'd be great. 'Nos' would be useful too depending on the situation he is in at Sun'lun. I think defensively we aren't too bad at moment. We need a LB but I'd also keep Andy Taylor who I think could develop still. So a RB and a LB needed plus Nos and Seip.
I'd keep Monty; not sure on Harper yet but I'd lose Quinn who I think needs a move. I'd build the side around Willo if he is going to stay fit; if not, I'd get rid. We need a consistent midfield. Yeates suits me with Ward but I think we'd need a LW if we get rid of Quinn.
Cresswell is suitable for now and I'd keep Hendo. Evans and Camara would be better in a footballing side and I'd also keep Sharp in the mix. We don't need new strikers, we need to play to their strengths.
Five or six quality additions needed; plus a manager. That's going to be costly. We don't have the money to do it I fear.
