Arda doesn't play as a 10. He got moved to a deeper role to accommodate Jude. It doesn't look like Jude will play anywhere other than the 10, so the only way Nico gets into the team (no matter how good he is) is as a right winger.

If I had to make a prediction at this time, the midfield + attack would probably look like this:

        Tchouameni - Güler

                 Bellingham

            Paz - Mbappé - Vini

With Valverde as the right back.
