Having spent the first half of his season in France the Belgian arrived at Leicester City on a season long loan deal which also saw Adrien Silva moving to the other side.
The midfielder was very impressive in his short stint on the English soil and a number of English clubs are reportedly interested in the player. United lack a leader in the middle of the pitch and the 22 year old could be the perfect partner of Paul Pogba to push United forward.
The midfielder is likely to cost in the region of £40m and the Red Devils should take the move to secure his services. There had been concerns over his quality to adapt to the rugged nature of the Premier League.
But his transformation from the Ligue to the English top flight has been amazing and he has proven his worth this time. The former Anderlecht midfielder is very comfortable on the ball and thrived in the swift attacking combination which Leicester love to play.
The Foxes are trying to secure a permanent deal for the player and United should step up and hijack the deal.
