Manchester City goalkeeper Joe Hart insists they're capable of upsetting Champions League opponents Barcelona.

Manuel Pellegrini's men need to win by two goals to at least level the aggregate after losing the first leg of the last 16 tie at the Etihad Stadium.

Hart said: "The tie is not over and we'll go into the game remembering what we've done this season and what we are capable of and I think that's how we have to look at it.

"A positive performance is key and a result would be fantastic, but we need to go out there and show we can really play against the likes of Barcelona.

"We've shown what we can do when we beat Bayern Munich away in December and while it's going to be tough, it's not impossible.

"I felt we were there in the first leg, had sized them up and were ready to go, but stuff happens in big games and if you give a predator like Barcelona a sniff of blood and unfortunately that's what happens."
