The only similarities Wijnaldum has with Siem, is they both play in an attacking midfield role. For me, Siem is more about positioning, arriving late into the box, and off the ball movement to create space for himself. Wijnaldum is more about quick movement and pace to burst through from midfield and drive at a defence. If anything Wijnaldum is a variation of Moussa, which is why I believe he will be sold if Georgino comes in.
