The 36-year-old scored a trademark free-kick to defeat Ecuador in the final minutes on Thursday, but he was soon substituted and head coach Lionel Scaloni confirmed his main man had picked up an injury. Messi, who is pivotal to Inter Miami’s slim hopes of reaching the MLS playoffs, is a doubt to feature in La Paz on Tuesday due to the undisclosed issue. He was seen leaving the IMAXE medical centre on Saturday after being checked over by specialists, although Scaloni still hopes Messi can play some part in the second game of Argentina’s World Cup qualifying campaign. To prepare for the game at Estadio Hernando Siles, Argentina’s players have been given oxygen tubes to help deal with the effects of the altitude. The stadium is 3,637 meters above sea level, making it one of the highest stadiums on the planet and the Argentina players are sure to be gasping for air at times during the game. Brazil icon Neymar described the conditions as ‘inhumane’ during a 2018 visit. Liverpool midfielder Alexis Mac Allister shared a picture on Instagram from the team bus with his face pressed into the mask attached to his canister. Tottenham defender Cristian Romero was also seen holding one of the tubes when he left the bus. Liverpool star Alexis Mac Allister with one of the oxygen bottles provided for the team.

But news of an injury is sure to have caused concern in South Florida, although Scaloni did not seem overly concerned during his pregame press conference. ‘Messi is going to travel to Bolivia,’ he said. ‘He trained differently (than the rest of the team), but there are still two days left until the game and we will make the decision tomorrow whether he plays or not. The team is going to be similar to the one that played against Ecuador.’
