Watched again. Think it might have been him doing the tackling.
He can definitely tackle. Doesn't go to ground too often, though, he just knocks people off the ball. He's very strong.
Any stats you have to factor in the fact that he was playing mostly CM this past season and I don't believe he'll play there for us. He's a true defensive mid that will sit behind Gomes and shield the back line. His passing range is outstanding. He can take the occasional long shot, too.
He's still got some things to learn at DM IMO, but he's pretty darn good already. He seems like a good fit in terms of where he looks comfortable on the pitch.
