Well I'm guessing that the two loanees and the free are probably costing the best part of £2Million in wages (I don't know). I take your point that we should be able to buy a decent striker. Not sure how much when you say spend BIG. (Transfer fee? and wages).
I don't think we will finish there...
Looking on one of the Villa Forums (Villa Talk) many seem to feel that JB would make a better wing back(good) than a full back as his defending isn't great (not so good). Some say he would make a better midfielder (He could team up with Bruno). He is a confidence player, so he may have problems...
