Manchester United manager Jose Mourinho has admitted that his side were "not phenomenal but good enough" during this evening's 3-0 win over Young Boys in the Champions League.

Two goals from Paul Pogba and a third from Anthony Martial wrapped up a routine result for the Red Devils in the end, although it took time for them to grow into the game on an artificial pitch.

Mourinho voiced his displeasure at the plastic surface being allowed in the competition, and also talked up the importance of beginning with a victory in a group which also contains Juventus and Valencia.

"Job done. Not phenomenal but good enough. They were intense, compact and had self esteem. Then after the first goal the game was under control. We tried to score the goals that gave us the stability for the second half," he told BT Sport.

"It is important for us to win because probably every team is going to get six points against Young Boys. Now we have two important matches against Valencia and Juventus. They are very good opponents.

"There was probably some fears of injuries [because of the pitch]. I had some players who were feeling sore after training yesterday. People are more used to playing on great surfaces in England. The football is much more beautiful that way. Now the game is over, I can say I don't understand how you can play the best club football on an artificial pitch."

United are the early leaders in Group H, level on points with Juventus after the Italian champions overcame Cristiano Ronaldo's sending-off to beat Valencia at the Mestalla.
