But PSG are in a difficult position, needing to win at Old Trafford to keep qualification hopes in their own hands just three months on from losing the 2019/20 final to Bayern Munich.
Tuchel led PSG to victory at Old Trafford in February 2019, but that 2-0 win was rendered meaningless thanks to United’s historic 3-1 triumph in the second leg of that Champions League last-16 clash.
Rashford struck the winner that night, just as he did as Solskjaer’s side emerged 2-1 victors in October’s Group H opener in the French capital.
“We value him very much when he plays in England and not Parc des Princes, honestly, because (him scoring against us) gets a little bit annoying,” Tuchel said.
“The guy is a very young adult who takes his responsibility on and off the pitch very impressively.
“I have met him as an opponent three times and every time I’ve met a calm and humble guy and a nice person, which is amazing. I like this mixture a lot.
“For me personally, the sporting side is clear – he’s a big threat with his speed, with his ability to score, with his determination and his finishing.
“He’s very precise, taking shots inside and outside of the box. He is super rapid on counter-attacks and strong in the air with headers.
“He’s had a big impact and it’s nice to see guys like him from the academy having such a big impact in a big, big club like United.”
As well as Rashford, Solskjaer is also able to call upon PSG’s all-time top scorer Edinson Cavani just days after he inspired United to an outstanding 3-2 comeback win at Southampton.
“This determination is a rare characteristic for a striker of his quality – always ready to do everything for the team. He has a big physical impact, scoring comes very natural for him. He’s reliable 24/7. You can call him in the night and he’d be there to score and to defend.
“I’m happy for him personally that he could show this to all Man United fans in the last game against Southampton, where he was absolutely decisive for them.
“He does not need to show it tomorrow, we already know, so he can do a little pause! It’s not necessary to show us. If he plays, we must find answers for that.”
