I agree with you there about Gibbs and Santos, it was just unlucky that both were injured at the same time and the versatile Vertonghen would be an ideal player to cover all eventualities. My only fear with Santos is that he thinks he is a forward!
Bring in Vertonghen, M'Villa and another right back and Arsenal start to look very strong defensively.
Ideally another attacking midfielder wouldn't go amiss but the question is, will Arsenal spend that kind of money.
If Arsen can off load the crap thats draining funds from the club he might be able to bring in some quality for once.
If we can't sell, we can' buy and that's the problem!
