We have seen strange pictures with Argentina superstar, Lionel Messi, vomiting before or during games, but his father has played down any concerns about his son.
The 26-year-old was seen vomiting during Argentina’s 0-0 friendly draw with Romania in March, and also received a tablet from the bench during Argentina’s 2-0 victory over Slovenia in their World Cup warm-up match.
However, Messi’s father, Jorge Messi, has now confirmed that the vomiting is nothing to be worried about.
"This subject has been around for years now," he said as quoted by ESPN.
"The necessary studies were done at Barcelona. All the doctors say there is no need to be concerned. It does not just happen to him, but to other great athletes in other sports too.
"It is a bit about the stress, or a little stomach problem, but there is nothing else. There is no need to give it too much attention, he must take precautions and nothing else."
Argentina coach Alejandro Sabella echoed Jorge Messi's words, putting the vomiting on Saturday down to "anxiety more than anything," while Lionel Messi himself has previously played down the problem.
Argentina will face Bosnia and Herzegovina on Sunday, 15 June.
