A late Lionel Messi masterclass at the Nou Camp left Liverpool’s hopes of a second successive Champions League final dangling by a thread – but there have been enough dramatic turnarounds in recent seasons to suggest all is not lost for the Premier League side.
The prospect of an all-English final may look slim after the Reds’ 3-0 first-leg defeat and Tottenham’s 1-0 home loss to Ajax.
But some of the biggest moments in Champions League history involve teams fighting back from big deficits to defy the odds, including a remarkable collapse from Barcelona last season as they squandered – you guessed it – a three-goal first-leg lead.
Here, we take a look back at some of the turnarounds that suggest anything is possible, and you can vote for which one you think is the greatest comeback.
