Sanchez is optimistic but Gunners fear he could miss big United clash
Arsenal could be without playmaker Alexis Sanchez for their Premier League clash with Manchester United next week after he was forced out of training with Chile.
Sanchez, 27, suffered what the Chilean medical team described as a "low grade muscle injury" as the team trained in preparation for their World Cup qualifier against Colombia tonight.
The Gunners midfielder will definitely miss that match, and his involvement in next week's game against Uruguay is also in serious doubt.
There is the possibility that the Chile medical team could decide to send Sanchez back to London where he would recover with his club.
Arsenal fans will be concerned given the form Sanchez has found himself in for the title hopefuls, and his absence against Jose Mourinho's United would be a big blow.
Gunners boss Arsene Wenger will be hoping that the Chilean, who has netted eight times so far this season, will recover in time for the trip to Old Trafford on November 19.
But Sanchez himself downplayed any fears, saying: "It is hurting a bit but I'm fine. I'll be back for Tuesday."
