Not trying to pick on you Mike, but you mind if I ask why you don't rate his ability going forward? We're talking about a guy who had more successful passes in the final third than any other Eredivisie player in 2016 -- and that was on a defensively-inclined team, where motivating forward campaigns was significantly trickier than it is at the top. He strikes me as such a technically gifted player for his age. Some of his decisions and touches are truly brilliant, and hard to find in a player of his experience -- knows what he's going to do with the ball long before it gets to his feet.
I worry that for some people (not directed at you, Mike) there's a preconceived notion about him because he's Irish. They imagine a lot of grit, determination, etc. etc. (fill in your own Irish stereotypes). Whereas if he was Spanish, Croatian, etc. he'd be lauded for his technique & vision.
Regardless, I wish he was staying for pre-season under Pep, because I do feel he's ready to be eased into our first team. But the backlog in our central attacking midfielder department is formidable, so if he goes out on loan good luck to the lad.
