Arsenal forward Alexis Sanchez sitting on the pitch after being fouled during the Gunners' 0-0 draw against Middlesbrough at the Emirates Stadium yesterday.
The hosts endured a frustrating match against a stubborn Boro side, and had a goal correctly ruled out for offside in stoppage time.
Although the draw lifts Arsenal past Manchester City to the top of the English Premier League table, City can regain the lead with just a draw against Southampton today.
