I don't believe for a minute that he's injured.
He'll be 27 when the world cup comes around, perhaps his only chance to play in a World Cup and he's blowing it. Southgate already doesn't like him, he's got a 21 year old daughter, he prob hates the thought of blokes like Jack and the way they treat women.
If Jack starts getting benched at City then I can see him not making the WC squad at all.
And for those saying that maybe nothing happened with Jack and Emily. Behave! Of course they're shagging. The 'just friends' thing is a legal disclaimer because the publication can't say for certain that they're intimate.
If Sasha's friends and family are saying anything to her other than 'end this, you're better than that,' then they are part of the problem too
