Lionel Messi marked his return to the Barcelona starting line-up with a hat-trick as a 4-0 win over 10-man Manchester City preserved a perfect start to this season's Champions League campaign for Luis Enrique's men.
Messi came off the bench following a groin injury to score in the 4-0 weekend win over Deportivo La Coruna and he netted a 17th-minute opener at Camp Nou on Wednesday.
City boss Pep Guardiola was back at the ground with which he will for ever be inextricably linked and his team posed plenty of questions either side of Barcelona going in front, until a mindless red card for Claudio Bravo resulted in the game racing away from them.
