That's probably because Udinese were awful and squandered them all either by taking too long on the ball allowing Inter players to get back to defend or by making rushed passes straight to Inter defenders.I don't remember many Udinese attacks like you describe but certainly the goal they scored was a counter we dealt with badly and we were very open on that Success chance.
I think he tapped Barella's heel as well, which I'm pretty sure was the main cause for Barella losing his balance.Yes Udogie shoved Barella. Not sure if Lukaku did an awful lot earlier, wasn't clear. Had it been awarded it would have been a pk and red card, would have made an Inter win much simpler surely.
