Eriksen works in all places when he has smart passing and quick movement around him. I think, ideally, he would be able to drift and switch with a left-sided player at will and choice. When our midfield is not slowed down by ball carries like Dembele, it allows Eriksen to drift into spaces, receive quickly and turn the play. Likewise, Soldado is excellent when Eriksen is free. Chadli is technically strong so hopefully we are now seeing his confidence return to give him the impetus to play faster. One of the reasons I love Bentaleb, and think he is potentially a huge player for us, is that he moves the ball quickly and crisply from deep positions; I think Eriksen benefits greatly from this...
Bentaleb isn't enough to work with Eriksen, he's good, but to me our line up is
Lloris
Back 4
Sandro/Bentaleb
Chadli - Eriksen - +1 (this +1 has to be someone that plays the ball quickly with eye for a pass, ideal world = Lamela)
Ade - Soldado (If both aren't available, play a wide player or maybe Siggy to allow Eriksen to fit behind the main striker)
