Defeat to Chelsea could be a turning point for Barcelona, warns Pique

The Catalans have drawn twice in a row in La Liga, and the defender believes that defeat against the Blues could derail their excellent season

Gerard Pique has told to be wary of the threats posed by ahead of next week's last-16 tie.

Barcelona travel to the Premier League champions for the first leg of their clash on Tuesday, the Catalan giants having seen their comfortable cushion atop cut to seven points after back-to-back draws.

Chelsea and Barca have a rich shared history in the Champions League, having faced each other 12 times in the tournament since 2000, most recently in the 2011-12 semi-finals.

There have been four Chelsea wins to three for Barca during that time and although the Blues have made a poor attempt at defending their league title, Pique believes Antonio Conte's men should not be underestimated.

"Expectations are maximum," Pique said on Thursday. "We go out as favourites, with a chance to win.

"I know the atmosphere is positive, very favourable, everything looks good, but I think we have to be more prudent.

"We have to learn from experience, what has happened in recent years, and know that one bad day could see you knocked out of the Champions League.

"A bad result against Chelsea could turn the good season we are having into one that's not so good.

"We know we are in a good position in the league and the and we go to London in the Champions League looking to win, get through and progress in the competition."
