Manchester City face an improbable task to progress to the Champions League quarter-finals after Barcelona capitalised on Martin Demichelis's 53rd minute red card to dominate at the Etihad Stadium on Tuesday night.

Argentina forward Lionel Messi, who was fouled by his countryman Demichelis to concede the penalty, stepped up to coolly send Joe Hart the wrong way to open the scoring.

Dani Alves then put the game, and possibly the tie, out of City's sight with a strike two minutes from time after a neat one-two with his fellow Brazilian Neymar, who had come on as a substitute.

The teams meet again at the Nou Camp in three weeks time.
