I think the marriage break up was a factor but if he was enjoying his football and we on a roll again I doubt he'd leave. Would have probably just got his head down and focus on football. But he wasn't past it. Not to the point where he was no good to us. Our shitty defence kept leaking goals and he was building on a good relationship with Ade. Henry may have been able to keep the guy humble.
That defence has been a thorn in our side for years and
Wenger's tactical philosophy on defending hasn't help either. He used to play a 5 man midfield with Diaby and Eboue on the wing for pete's sake. It has taken him too long to figure out certain things about our formation and playing certain players in the right position. It's been a huge waste of time. We didn't need to lose Henry to come to such conclusions. Our defence has been a shambles for a long time, we haven't had fast wingers for a long time and we need strong and mobile box to box type players in the midfield. We've known this for ages but it has taken him ages to fix the problems. Now that the defence looks sorted, we've lost our best attackers.
