Trending Pep Guardiola Manuel Pellegrini Manchester City Manchester United. Sergio Aguero joined his best friend Lionel Messi in an amazing gesture to a fan. The Manchester City striker looked on as a supporter dressed in a Barcelona top ran on the pitch at the end of Argentina’s 5-0 Copa America win over Panama, in Chicago. The fan made a beeline for Messi, who had scored a hat-trick in the win which secured their place in the knockout stages – with City pair Aguero and Nicolas Otamendi bagging the others. But stadium staff at Soldier Field tackled the pitch invader before he could get near to the Barca superstar, pinning him to the ground. Aguero calmed down the situation by walking across to the fan before Messi also joined in, embracing the fan as he was lifted to his feet. Kun took the fan’s mobile phone from him and took a photo of him with Messi before handing the phone back as the fan was led away.
