For the lazy ones:
Manchester City can confirm Gabriel Jesus suffered a medial collateral ligament injury during the 0-0 draw with Crystal Palace on Sunday.
He will undergo further examinations in the coming days to establish the extent of his lay-off.
We wish Gabriel a speedy recovery and we will keep you updated on his progress via the Club's official channels.
I read that as out for at least 2 months, worse injury news possible.
Sanchez now needed asap, or someone else.
