Messi scored the opening goal of the match at the Stade de France, but was withdrawn at the interval complaining of a hamstring problem, and will be assessed over the coming days.

"I hope he [Messi] is not injured, I hope he's fit for any game coming up, we wish him well," he told ITV.
"I was obviously very happy to start. The manager's always shown a lot of confidence in me, especially in big moments, tonight was a big moment for the club and I was happy to start."
PSG rallied after half-time and Zlatan Ibrahimovic cancelled out Messi's opener on 79 minutes, before both sides traded late strikes through Xavi - from the penalty spot - and Blaise Matuidi.
The result leaves everything to play for at Camp Nou next Wednesday, and Beckham, a surprise starter in the match, believes his side were well worth a draw.
"I think the draw was deserved," he added. "Obviously it was always going to be a game where they had a lot of possession, they have an amazing team and they played very well.
"In the first half, especially in the first 10 minutes, we had a few very good chances, if we'd have put one of those away then things might have been different but then they got their goal. Then it was a real battle.
"It's better than it was at 2-1. It's going to be difficult, but there's no reason we can't go there and get a result."
