Paul Pogba believes Manchester United are improving and can only get better following three successive victories.
The midfielder was seen as the key man in that Young Boys win, earning the praise of Jose Mourinho, who was impressed with Pogba's "class" on the day.
Luke Shaw also heaped praise on the Frenchman, saying Pogba ranks among the best midfielders in the world.
Reflecting on United's form ahead of Saturday's visit of Wolves, Pogba said: "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."
United have nine points from five Premier League games as they prepare to welcome Wolves to Old Trafford.
