I don't count that as cheating. It is just a smart move. He got slapped. Barely but he did. And it put him out of balance. For me it is a foul. Body on body is different thing but contacts with arms and legs are fouls for me.
Remember our pen vs Villa? Minute before pen we should have got pen but our player stayed up. Then Pogba told him "go down". And in next moment Pogba got us soft penalty.
I don't know but in these situations i always remember Inzaghi's word; "when i feel contact, i go down". Like it or not, football became soft game so you adapt or you suffer.
