Would be a good sitting CM, backup for Casemiro and could play alongside him when we needed to be more solid in the middle and going back to playing with 2 DMs. Certainly a better defensive minded midfielder than Fred and McTom, or any we've been linked with this summer other than Caicedo. So its not a bad idea at all.
However he's found himself out of the Spurs team this season with their impressive start having mostly to do with the 2 CMs Sarr and Bissouma and Maddison right in front of them. So obviously a more ambitious idea would be to go for Bissouma or Sarr. They'd also cost far more money now which is why we're being linked with Hoj instead.
Edit - An extra note which may have gone unnoticed. I didnt notice it. His ball winning numbers were down last season from the previous seasons, but he got 5 assists and 4 goals. So he was more offensive last season than the previous seasons and had more end product than Fred and McTom, Amrabat, Caicedo, Lavia etc
