Cavani scored 200 goals in 301 matches for PSG before leaving over the summer and joining United, whom Tuchel believes have a gem on their hands.

“They’ve got a great personality, like with many of the biggest players of the game – it’s the same with Edi,” the PSG head coach said of the 33-year-old Uruguayan.

“Very polite, almost a bit shy. Hard, hard worker. He will be there in every training (session) first minute until last minute. Every game from first second until last second. You can totally rely on him.

“He’s living for goals, living for scoring. When he scores, when he has the confidence, he’s one of the (best) number nines in world football.

“Hopefully he will show, not (on Tuesday) but from Wednesday on, he can start to convince all of you. I have nothing against that. But (on Tuesday) it’s not necessary to prove me right.”

Tuchel will not have anything to worry about on Tuesday, though, with Cavani not in the United squad, having only trained with his new team-mates for the first time on Sunday due to UK quarantine regulations.

It was in Paris that Solskjaer all but secured the United manager’s job on a permanent basis when overseeing a record-breaking Champions League last-16 win 19 months ago.

No side had ever overcome a two-goal home loss and progressed from a knockout match in the competition’s history, but United rolled back the years to seal a memorable 3-1 triumph in March 2019.

“Obviously we don’t have very, very good memories,” Tuchel said.

“We had a good result (a 2-0 win) at Old Trafford. In the end it wasn’t a very great outcome for us, but we’ve had a very great run last season for the Champions League.

“Now, of course, it’s a challenge not to think about too much last season, nor about two seasons ago. This doesn’t help.

“Now we have to overcome these difficulties, we have to show what we are able to do now and we start this new Champions League with zero points and we have to play.”
