Marcel Desailly believes it’s do or die for PSG at the Parc des Princes.
The encounter pits two clubs brought to the fore of European football by moneyed ownership in recent history.
And ambition is of course great for either side. The Blues are looking to bring the continent’s top prize to West London for the second time in three seasons as Les Parisiens chase down their first title in the elite competition.
But despite palpable suspense surrounding the double-barreled tie, former Chelsea skipper Marcel Desailly thinks it could be decided after just 90 minutes.
In favour of Jose Mourinho’s men, no less.
Desailly said in speaking to talkSPORT: “The decisive game will be in Paris. If Chelsea were to score or win away from home I do not think PSG would be able to overturn the result in London.
“The numbers speak for themselves at Chelsea’s ground, PSG will not be able to win at Stamford Bridge.
“The Parisians hope to reach the semi-finals at least, however.”
Desailly has his personal reasons to doubt Laurent Blanc’s side.
Aside from his Chelsea past, the Frenchman also spent a season with PSG’s hated rivals Marseille - with whom he won the Champions League in 1993.
Yet as Desailly aptly pointed out, the Blues are nearly unbeatable at home.
Jose Mourinho has still never lost at Stamford Bridge on the Chelsea bench in the Premier League. And though the Champions League is a different animal - Basel won in West London in September - it’s clear how formidable the Portuguese’s men are on home turf.
The past should quickly be forgotten as the clubs come to blows, but Desailly’s words remain a strong warning to PSG.
Because in his view, Les Parisiens will surely be watching Chelsea move on to the semi-finals next week if they can’t get the job done on Wednesday evening.
