I wanted us to go for Lavezzi in the summer after we missed out on Sanchez. For £8m and around £65k per week, I'd definitely take him despite being nearly 30. The only thing that makes me take a step back is the prospect of Tevez being available for free in the summer. Could we have both...?
I wouldn't sell Enrique either. I think he is a very good LB that competes very well with Moreno for a place in the team. If we were to sell him, I'd want to see a LB arrive first, we need to be aiming for two decent players in every position.
Agree that we need to have some strength in depth but Enrique is not good. Take away his ability to shield the ball, he offers very little. I know I'll laughed at, but Cissokho was actually a good defender - granted, he was dog sh*te on the ball but defensively, he was sound.
