Lionel Messi is a doubt for Barcelona’s opening Champions League clash against Celtic next week with a groin injury.
Messi aggravated the injury on his return to international football with Argentina last week, where he scored the winner in a World Cup qualifier against Uruguay.
Lionel Messi was supposed to feature in Argentina’s next qualifier against Venezuela on Tuesday but instead returned to Catalonia where he underwent scans over the weekend.
Barcelona said in a statement on Monday: “Tests conducted today on Leo Messi have confirmed that they player is still having trouble with the left adductor muscle.
“He has been recommended to lighten his training load over the next few days and his availability will depend on how the issue progresses.”
