The Frenchman, following a wonderful switch of the ball from his left to right foot under pressure, rifled his side into the lead late in the first half.
He added a second from the spot before unleashing a dominant second half performance during which he claimed an assist for Anthony Martial.
Speaking after the game, Mourinho expressed his delight at the way Pogba influenced the game in Switzerland.
“I don’t think he can score goals every match,” he said. “But the goal he scored today, first of all, is not different than the fantastic save [Ben] Foster had in the last match [at Watford], so if he starts arriving in possible scoring positions that can be a plus for the team, so I’m happy with that.”
“The team had good stability in midfield to allow him to go to these kind of positions and I’m happy with the good, solid performance of the team more than any individual.
“We knew we needed to win this match, we knew it was very important to go to the next three matches against Valencia and Juventus twice with these three points and we did that.”
Sometimes there are games where it becomes clear just how much better Pogba is than everyone else on the pitch.
Man United scrambled during the opening 30 minutes, just trying to get their bearings on the plastic pitch, and it was Pogba who melodically guided them into a period of pure domination, shielding and caressing and launching the ball in one swift motion to give them the lead.
After that, it was something of a training exercise for Pogba, roaming forward with the ball and allowing the game to run at his pace. Make no mistake: he can be a truly magnificent driving force, capable of taking the spirit and legs out of opponents.
Supporters know that their team will always benefit from having Pogba driving forward in attack. Mourinho has to ensure it keeps happening.
