Three ways Allegri can fit new Milan signing Nkunku into his starting XI

Milan were expected to bring in a new centre-forward for most of the summer transfer window, but Nkunku, more of a second striker, winger or trequartista, was the closest they came. 

He is expected to be competing for positions in the Milan line-up alongside the likes of Pulisic, Leao and Santiago Gimenez. 

So far this season, Allegri has opted for two different variations of a back three system. He has utilised both a 3-5-2, initially with Leao and Pulisic in attack, and later a 3-4-2-1, most recently with Alexis Saelemaekers and Ruben Loftus-Cheek playing in the supporting roles behind Gimenez at centre-forward. 

As per TMW and La Gazzetta dello Sport, Nkunku is likely to play as one of the two centre-forwards in a 3-5-2, likely alongside Leao or Gimenez. 

In a 3-4-2-1, he is more likely to play in one of the trequartista roles, likely alongside Pulisic or Saelemaekers, and likely playing behind Leao at centre-forward. 

There is also a chance that Allegri elects to switch to a 3-4-1-2 system at some stage of the season, in which case, Nkunku is capable of playing either as a centre-forward, like he would in a 3-5-2, or in the trequartista role behind a different combination of Rossoneri strikers.
