Manchester United midfielder Ander Herrera has described as positive the recent Clean sheets United have had in all competitions.
United have kept five clean sheets in six games, conceding last against CSKA Moscow on 21st October.
Herrera who came as a second half substitute said that in order to have a great season, too many chances should not be given away.
"It’s a positive that we’re not conceding goals," Herrera told ManUtd.com. "We saw it last year with Chelsea; I don’t think they scored too many goals, but they didn’t concede many either. That’s important when you want to have a great season, you can’t give away many chances.
"I think we controlled the game against Moscow. We only conceded one chance, which was good. We also created 10 or 12 chances, which was also good – we want to control games and did that today."
He also revealed his relief at seeing United hit the back of the net after a while, and praised goalscorer Wayne Rooney.
"Of course there was relief, but Wayne is one of our most important players. He’s our leader, our captain, and we’re happy when he scores. When he doesn’t score, he fights for the team and that helps a lot as well," he said.
"He’s very important, and I think he has a very strong mind. When he doesn’t score, he keeps fighting in the same way, and that’s important for us. I always say the same: he’s one of the best players in the world, one of the stars, and he’s not selfish. For us, it’s very important when he feels good. When he scores, of course it’s better for everyone, but if not he still fights.
"I can only say what I see, and what I see is that he gives everything. We say the same thing every day: he does a lot of things for the club and the team. Of course he’s one of the best in the world, his trajectory is unbelievable.
"The way he fights, the way he trains and the way he gives his opinion to the other players. Maybe those on the outside only see what’s on the pitch, but he’s also very important off it."
