I agree with you that the primary partnership is currently JPvH and Igor, but that's not really what I meant.
In the context of the game we were messy going into the final stages. A combo of Dunk coming on and the change of formation that it precipitated gave us back control. I dont agree that it made us look unbalanced. I liked the 3 at the back. It stopped the rot. The entire end of the game was us pinning them in their own area (admittedly to no great ultimate effect) but it was secure, with Dunk instrumental in making that shift.
