Eden Hazard claimed if Chelsea lost their 10 point advantage at the top of the league it would be as much of an upset as PSG's 6-1 capitulation against Barcelona.
Chelsea already have one hand on the Premier League trophy, leading by a sizeable margin with only 11 games left in the campaign.
But the Blues star iterated that the improbable certainly is possible, and likened their position at the top to PSG's four-goal lead they took in to the second leg of the Champions League last-16.
'But you saw what happened in the Camp Nou, Barcelona,' Hazard told The Times, recalling Barcelona's heroics as they overturned the deficit to reach the quarter-finals.
