Would give both of them a chance, it's the sensible thing to do, if they are both prepared to come back. However neither of them were great when we had them so they will have to step it up a level, anyway both are likely to be better than what we have at present for their positions so we have little to lose by giving them a chance to prove themselves. In addition as said already their style of play would seem to be suited to tiki taka so it could work out.
