A delighted Barcelona manager Luis Enrique said that Messi treated City players like "school yard" children.

 

"We have seen the calm that Messi has to finish inside the area as if he was in the school yard. If there is anything you can expect of Messi, it is that. It doesn't matter how many days he has been out or the games he has missed," the Spaniard told AFP.

 

Former Barcelona and current City manager, Pep Guardiola, is surely under pressure as the English club at present stand second in Group C, five points behind leaders Barcelona and a point ahead of Borussia Moenchengladbach.

 

Messi, who played only his second game after returning from a knee injury, opened the goal chart in 17 minutes. He added another two to complete a hat-trick in the second half when City goalkeeper, Carlos Bravo was sent off.

 

"It is always difficult to play in Barcelona with 11 players and with 10 the game was over. We created enough chances; we arrive at the byline many times, but with their strikers when they arrive they punish you," Guardiola said.
