Oveideo has no out and out winger in front of him we have three wingers Lennon {On top form} delboy a handful - and KM who knows were the goal is!
If we do away with a defensive midfielder the service to Lukaku would be 100 % increased the speed of our moves would be faster ,, and as you say they could rotate wings as the game progressed if we go 2-0 up the take one off and put a defensive midfielder in late on to see the game out, also I feel RNB would have an outlet for his through balls as he at times is our one man midfield going forwards with pace!
But The Clev isn't a DM.
