Arsenal defender Andre Santos has been ruled out for around three months with an injury to his right ankle.
The left-back sustained the problem in last week's 3-1 Champions League defeat against Olympiacos in Greece.
A statement on the club's official website, www.arsenal.com, read: "We can confirm that, following investigations and subsequent medical opinions by club specialists, left-back Andre Santos will have surgery to repair ligament damage in his right ankle sustained in the game against Olympiacos last week."
