The Arsenal star has played a number of matches recently and is currently suffering from a minor calf injury, which worsened during his country’s 1-1 draw with Colombia last Thursday.
Reports suggest that Sanchez has been unable to train over the weekend, yet his importance to the Copa America champions means he could play regardless of whether he is 100% fit.
Speaking to reporters on the situation, Chile boss Sampaoli hinted as such: “Alexis has a pain in his calf and we will wait until the last minute to see if he is ready to play.”
Arsenal boss Arsene Wenger will be monitoring the situation carefully, and tensions could grow between club and country should Sanchez return to North London a little worse for wear.
While the World Cup qualifiers evidently have huge importance, a potential injury to Sanchez could seriously derail the Gunners’ season, and his situation is notoriously delicate.
The talented forward has played an enormous number of games over the past 18 months, having featured in both the World Cup and Copa America in successive summers, with little rest in-between.
Wenger will want his star man to use the international beaks to recharge his batteries somewhat, not feature more than necessary and increase the risk of burnout or a potential injury.
