José Mourinho was unhappy with elements of his Manchester United’s side performance against Basel, despite the Reds running out 3-0 winners against the Swiss champions in their Champions League group stage opener.

Goals from Marouane Fellaini, Romelu Lukaku and Marcus Rashford wrapped up the three points on a soggy night in Manchester, but the United boss felt that complacency slipped into his side after they went 2-0 up.

Speaking to BT Sport after the match, he said: “Three points are important at home. Until 2-0 we were very stable, we played with confidence.

“After 2-0 everything changed, we stopped playing seriously and stopped making right decisions. We could have put ourselves in trouble.

“We were playing fantasy football, Playstation football. I don’t like it, flicks and tricks. We gambled and you have to respect your opponent. I don’t know if goal difference will play a part. We lost position, our shape, we lost balls in easy situations. I didn’t like it, the players relaxed too much.”

However, Mourinho reserved praise for Fellaini, with the Belgian having put in a terrific performance after coming off the bench in the first half for the injured Paul Pogba.

“I keep saying the same about Fellaini,” Mourinho said. “He is a player with special qualities and he gives me multiple areas of action. He is one of my most important players.”

As for Pogba’s injury, Mourinho said this: “I haven’t spoken with the medical department, this is why we have a squad, we won’t cry about injuries.”

Meanwhile, Marouane Fellaini and Romelu Lukaku both had their say on the win during their post-match interview with BT Sport.

Fellaini said: “It was an important game for us, first game in the Champions League, it’s always good to win. I feel good. He [Mourinho] knows what I can do, he knows my qualities, he counts on me, so that is important for me. On the pitch, I give everything.”

Lukaku said: “I’m just delighted with the win, for the team, we wanted to win after the little slip-up at Stoke City. We needed to bounce back and win today. The football was not great, but we won and that’s the most important thing. We’re working hard, everybody’s scoring, defensively we’re not conceding. It’s still a work in progress but we’re doing well now.”
