Wenger facing Real test
Already with so many key men still injured, Wenger must also do without Togo striker Emmanuel Adebayor, who is cup-tied.
Forward Jose Antonio Reyes is a major doubt after suffering bruising to his leg against Bolton last weekend, but it is at the back where Wenger has real selection concerns, with Mathieu Flamini set to continue on the left side of defence as both Ashley Cole and Gael Clichy are still not fit.
