Cavani signed for the Red Devils on transfer deadline day though has not featured since March and is obviously lacking match fitness.
So much so that he has been left out of the Uruguay squad for the current international break and is hard in training to improve his fitness.
The 33-year-old is currently self-isolating for 14 days after arriving in the UK from France on Sunday and will not feature against Newcastle.
United play PSG in their opening Champions League match on October 20 with Cavani’s last game having come for the Ligue 1 giants in the European tournament in March.
And the Daily Mail claim Cavani is desperate to face his former club, who he left at the end of last season, despite being likely to only have one training session with his new team under his belt.
Manchester United boss Ole Gunnar Solskjaer can’t wait to see Cavani at Old Trafford, outlining the four different things he gives the Red Devils.
Solskjaer said: “Edinson is an experienced ultimate professional who always gives everything for his team.
"His goalscoring record for club and country is fantastic and we are delighted to sign a player of his calibre.
“He’ll bring energy, power, leadership and a great mentality to the squad but, most importantly, he’ll bring goals.
“He has had a brilliant career so far, winning trophies at almost every club he has played for, and he still has so much more to give at the highest level.
