United must first defeat PSG in the last-16 stage, with the first leg to be played tonight at Old Trafford.
The Scotsman said: "Yeah, without a doubt.
"The Real Madrids and Barcelonas of, old who everyone fancied to win it, they're are not quite where they used to be.
"It's very open, and Man United are hitting form at the right time.
"And I think worse teams than this Man United team have won the Champions League in previous history, or at least get to the latter stages of the finals.
"I have seen worse teams go all the way. Sometimes in this tournament it's not necessary the best team that wins it, it's the in-form team.
"They've definitely got the capabilities, they've got the match winners, and Ole definitely has got that Manchester United mindset. He'll be thinking: 'We can win this competition.'
"The Old Trafford crowd will be absolutely rocking tonight and I think it could take them a long way."
