Balance

Simply put, the Ghanian is the most natural replacement.

Yedlin is more of a right-back and has so far looked comfortable in that role, providing an expansive overlap in order to further break behind enemy lines. Perez, meanwhile, is best suited to a floating role.

With that in mind, the on-loan Chelsea midfielder would give the most balance in hugging the touchline, allowing Mo Diame to wreak havoc in the centre of the park.
