Xhaka confirms to sky sports it was a clear penalty, he made contact with his knee, and he has no complaints.
I’m sure that’s the proof you need, straight from the horses mouth.
What about that blatant hand ball ? Disgraceful.
Erm - that's not quite what he said is it?
https://www.sportskeeda.com/amp/football/clear-penalty-xhaka-admits-to-zaha-foul The Switzerland international initially protested to referee Martin Atkinson but accepted he was in the wrong afterwards. "It's difficult. I think it's a clear penalty," Xhaka told Sky Sports. "I touched him in the knee. "The referee gave a penalty. That's football."
'It's difficult, I think...' Hardly a hands-up admission is it? And yes - his knee did touch him, because Zaha threw himself into it - he was already half way through his dive before the knees touched.
