After making a poor start to the season, losing to Brighton and Tottenham Hotspur, Manchester United have now refound their form.
The club have won their last three matches against Burnley, Watford and Young Boys - and Pogba believes that the team are now mentally stronger.
Pogba scored twice and set up the other for Anthony Martial in Switzerland, and says even those squad players who have come into the squad recently look at home under Jose Mourinho.
Pogba told 'Sky Sports': "Obviously when you win you are happier, mentally we are stronger we get better, we change the team but even the players who come in feel already like they are in the team, and that's all we need.
"It's a very important win because it was the first game in the Champions League, we needed to start well and we did. We had the result we wanted, maybe the performance should be better, but we have the result and three points.

"So I'm very happy to score and be decisive in the win and for the performance of the team. If I can do it, try to help the team as much as possible, if I can score and assist that is great."
