We tried him up top last year when Kane and Son were out and it wasn't good. He just kept throwing his hands up in the air when the ball didn't land at his feet. He doesn't have the pace to beat good defenders, or the ability to hold the ball up effectively.
I wonder if Dele even knows anymore what his best position is?
Are you forgetting the goals Dele scored when Mourinho first joined? Yes, his form dropped off once Son and Kane were injured. Which is hardly surprising since he was now receiving passes from Winks, Sissoko, Lo Celso and Moura - who between them have setup about 3 goals in the past 2 seasons.
19 goals scored this season. 1 measly assist from our midfield. Outside of Kane and Son, all our assists have come from new signings (Doherty, Regulillon, PEH).
Moura, Bergjwin, Ndombele, Lo Celso, Winks, Sissoko offer nothing in terms of the final pass. It is no surprise whatsover that Alli's "form" dried up when Kane and Son were out; and its no surprise that the team's form dried up when Eriksen checked out.
How would Dele do with Kane/Reguillon/Doherty/Bale providing the final ball?
