Barcelona manager Luis Enrique has claimed that his side are not clear favourites to beat Manchester City and reach the Champions League quarter-finals.
The Blaugrana are aiming to reach the last eight of the competition for a ninth straight season, while City have never gone beyond the last 16.
Enrique told a press conference ahead of the first-leg clash: "I don't think there is a favourite [in the tie].
"It is dangerous to speak of favourites in the Champions League - you have to demonstrate yourself on the field."
Barca beat City 4-1 on aggregate at the same stage last season.
