Do you mean when he shoved their player away because he was blocking taking the free kick?
Didn't see anything wrong with that and it properly got the crowd going - mostly because he and Moyes both got booked i think
Yep, he didn't start it but his delivery did get noticeably worse after.
I'd say getting in as a utility player is probably his best chance to be honest. I like him, I think he's a good solid player, but as central midfielder I think he's probably miles away from the England team. If he gets a reputation as being someone who always does a good job and plays at a high level wherever you put him he may find himself being seen as a good option to take tournaments as it frees up space for more matchwinner types if you have a couple of players who cover multiple positions.
He's not getting anywhere near the England squad as a CM. Anderson, Rice, Wharton, even Bellingham are all on a different planet to him there.
Will he get closer as a RB? He does very well for a midfielder, but it's not the same.
He doesn't make overlapping runs or get to the byline, the things we complain that
O'Brien doesn't do. He's got better delivery and can hold and pass the ball but it's still a stopgap.
Not english so I don't know much about his competition, but I imagine if you had the pick of the country you'd still pick two RBs over a midfielder who can play there.
I think he has a better chance by playing and improving at CM every week.
