One of the things I've learnt over the years is, even playing one player out of position can be enough to unbalance a team and unsettle it's rhythm. If players don't have confidence in the system they are playing or the position they are played in, they will often run around like headless chickens and not be as effective as they have been seen to be before. Sometimes it is better to play a less capable person in their natural position to keep the balance. That would mean possibly playing Bori down the right. If that is not a suitable alternative then the whole system needes to be changed. Steerman (on his day) is a capable wing back (IMO), therefore try a 5-3-2 formation, which I think would also suit Clemence a lot better. You need a play-maker, a defensive midfielder and an attacking midfielder to keep the balance in that formation.
Personally, I would play Hume and DJ up front. From the games I've seen, I think they would be far more of a threat.
