He had a rough patch recently when he made silly mistakes defensively but even offensively he wasn't the same Brana that started the season brilliantly. I think he looks better now. You can't expect every player to be perfect at everything. It's a trade off most of the times. If he's going to contribute like this offensively he can be excused for some of the mistakes he makes, although not all of them. Plus he is one of the experienced like Drogba and Terry, which makes him very important for us.
