A quick tidbit I found on him:
"Praet was tipped for big things when he made his Belgium debut four years ago, but his progress has been more gradual than expected after leaving Anderlecht for Sampdoria in 2016.
Playing style A tireless midfield all-rounder, Praet forms part of a balanced unit for Sampdoria alongside the combative Lucas Torreira.
He is strong on the ball, eagerly jostling for possession, and has the vision to open up the opposition in the final third.
Although comfortable receiving the ball under pressure, the 23-year-old can occasionally hold on to it for too long instead of looking for an early pass.
He displays an assiduous work ethic, however, tracking back to thwart counter-attacks and showcasing his impressive stamina at both ends of the pitch."
I'd be happy to finally have a Belgian back in our side, but I'd think Praet's compatriot Torreira has more of the qualities that we need here. It's possible that Praet is either a Wilshere or Ramsey replacement.
