The jury's out on me for Dele's best position. I felt last season that he was still trying the skills rather than do the simple thing in deeper positions and, despite his work rate, at times was bordering on a liability defensively.
I think the World Cup helped him develop as Southgate's naivety sacrificed his attacking flair and turned Dele into a water carrier. The England manager allowed Young to get away with never getting chalk on his boots in wide left areas and also allowed Maguire to keep pulling Young in to mark his man defensively. What that left was Dele running round like a madman trying to cope with 2 or 3 players coming at him. In the end against Croatia, it was a complete disaster, and most pointed the finger at Dele for having a "poor World Cup". Some even said that Dele shouldn't be in the England team. In reality, he was just as confused as we were in what he was told was his role in the England setup versus what happened every time he stepped onto the pitch due to tactical suicide by the manager.
What we're left with is a better player. Dele can play as a false number 9, as an attacking creative midfielder and he can also play as a box to box or deeper midfielder. He has it all and Poch and Spurs fans knew that anyway. We just need to see more of Winks, Eriksen and Dele together and let them express themselves.
I'm still not convinced Southgate has a clue how to use Dele, even though he has moved back to a flat back four and got rid of sub-standard players like Young. All I know is that when he came on against the likes of Modric, Brozovic, Lovren etc on Sunday you could see the respect and nervousness of those players in the first few minutes of his impact. For all of Dier's and Delph's efforts plus Barkley's guile, Dele looked at another level. I hope he doesn't go the same way as Scholes with England managers past preferring lesser players like Gerrard and Lampard over their most precocious talent.
