Nasri can become a reliable goal scoring midfielder, as effective as Lampard has been for Chelsea.
I don't expect him to be a playmaker or to dominate games, but he is very good at retaining possession, and if he's scoring goals regularly then he is indespensable for us. The problem for him has been a lack of movement and failing to take up goalscoring positions as well as not shooting enough over the last couple of months. However, in the last 3 games we've seen more of the Nasri for the first half of the season. His finishing was poor yesterday, but the bigger problem for me is when the player isn't even getting the chances to score. He made some great runs, and linked up brilliantly with RvP. He needs to be doing every game, and then he will be a 20 goal a season player.
I'm more worried about him not having signed a new contract yet. If he goes, we'll recoup what we paid for him, but that's about it.
