Not sure mate, Nasri looked pretty anonymous to me in many of the games he featured in post-Christmas last season.
But I do I understand what you're saying, and I feel as a general rule what you're saying works; young players take time to find consistency in their game, instead of the up and down performances we often see. However, there are exceptions to the rule, and I think Hazard, like Wilshere and a handful of others, comes into that category. Nasri, I don't think he does, he's just not quite as talented or as good. Hazard has got better and better every season he has played for Lille, and has been the top player in France for a while now, he also played his 80th consecutive match for Lille on Saturday, so he has played an awful lot of football for someone still only 20 years old.
I agree on Gervinho too, very good player and you were right to back him as you did. I just think Hazard would be ready to go if we got him next summer - he's an exceptional talent.
