Gutted for him, he's been back to his very best all season and the reason we tick. We are a different animal without him and as well as Nasri has been playing or as good as the replacements are that come in, City miss Silva more than anybody else bar Kompany. Having them both out for too long will be a major concern, just hope that the four weeks is playing it safe and not a case of what normally happens with our injuries when you can add at least a fortnight onto the original comeback date.
