French champions PSG need to beat Ole Gunnar Solskjaer’s United on Wednesday night to keep qualification hopes in their own hands, just three months on from losing the 2019/20 final to Bayern Munich.
Premier League giants Manchester United, meanwhile, need just one point from their two remaining Group H matches to qualify for the knockout stages, and beat PSG in Paris earlier in the season.
England forward Rashford was on target that night and also scored in Manchester United’s famous victory over PSG in 2019.
Discussing the threat of Rashford, PSG manager Tuchel said: ‘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.
‘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.’
The 33-year-old faces his former side having scored twice to help the Red Devils overturn a two-goal deficit to beat Southampton on Sunday.
Tuchel said: ‘His 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.’
