I don't see any point in having Bent in the team. What's the use of someone standing in the box if our problem is getting the ball in there in the first place?
A high scoring game - Villa will come out fighting and win.
If you're going to play Bent you might aswell start with him and give him 70 minutes or so to get into the game. He's hardly an 'impact sub'.
4-4-2 is coming back in a way, but it's not coming back with the classic two-wide, two-central arrangement, and it's definitely not coming back with goal poachers. It's coming back with weird forms of the diamond and strikers who drift wide to support the full-backs. There's no place for Bent in this type of system.
