4 Clubs who can stop Barcelona from winning the Champions League this season

#3 Liverpool

Liverpool FC v Tottenham Hotspur - Premier League

Provided that Barcelona scale through the Manchester United hurdle (which they are expected to), the next hurdle that would lie in their path would be Liverpool (who themselves are expected to qualify ahead of Porto).

The Reds have made steady progress since the appointment of Jurgen Klopp in 2015, growing from Premier League laughing stock to genuine title contenders in England.

Last season, the Merseysiders made it all the way to the final where they fell to Real Madrid and this term, they would be keen to take it a step further by winning the continental trophy for the sixth time in their history and the first time since 'The Miracle of Istanbul' in 2005.

Liverpool have been one of the most compact teams in all of Europe this season, with their impressiveness in taking Manchester City all the way in the Premier League title race serving as proof of that.

With an attack comprising the terrific trio of Mo Salah, Bobby Firmino and Saido Mane, Liverpool would fancy their chances of breaking Barcelona's defence, while Messi and co would have a bit more trouble breaching their rearguard marshalled by the ever impressive Virgil Van Dijk.
