The abuse and character assassination is uncalled for, especially suggestions he'd fuck over city to play for Belgium (he'd do anything for both). However I am in the camp that feels a replacement needs getting, like you I do think Otto will prove a good signing it's just his current partner Mangala is very much 50/50 on whether he can get better or stay as inconsistant as he's proving.
You would think by 2016 we'd be able to give him bionic upgrades.
It's injuries and the fact they will continue throughout his career and be harder to recover from as he gets older that basically means we have to look at replacing him sooner rather than later.
We probably won't see him much more this season and we need a leader who will be on the pitch and inspire others with their presence in the vast majority of games we play.
