Argentina star Lionel Messi could be playing in his last major tournament, but struggled in an injury-hit group stage.

The 36-year-old played in his side’s wins against Canada and Chile but was forced to sit out their game against Peru with a groin issue.

For the first time at a Copa America, Messi has failed to score in the group stage, although he did manage an assist as Argentina beat Canada 2-0 in their opening game.

But Messi has returned to training and the World Cup holders remain firm favourites to go the distance.

Up against Ecuador, whom they beat 1-0 in a friendly in June, Lionel Scaloni’s side will be expected to win.

The big question remains: will Messi finally manage to find his form?
