Arsenal could be without two key defenders for their crunch Premier League clash with Man City next week.
The Gunners lead Pep Guardiola's side by four points at the top of the table. Mikel Arteta's men could extend that advantage on Friday night with a win over bottom-of-the-table Southampton.
City are not in league action this weekend as they take on Sheffield United in the last four of the FA Cup on Saturday. It means the Blues' next league match is the Etihad Stadium visit of Arsenal next week, a match which Guardiola labelled a decider in the wake of his side's win over Leicester City last weekend.
