Lots of rumours around that Arsenal will sell Sanchez to Man City. He only has 12 months left on his contract & it doesn't look like he will sign a new one so Arsenal have no choice but to sell. The rumoured fee is 40,000,000 GBP.
This is really rumour, there is a little bit chance to happen this event, if Alex would change his current address then he would have been shifted to the German champion side, so Manchester City will not grip this striker, he is very important player for arsenal so they should not sell this fantastic player..
