Bruno Fernandes says Manchester United have “more identity” under interim manager Ralf Rangnick as they prepare for their first Champions League knockout tie in three years.

United face Atletico Madrid in the last 16 on Wednesday, with both teams enduring disappointing seasons heading into the first leg at the Wanda Metropolitano.

Atletico coach Diego Simeone said Rangnick had already turned United into a force.

“We’re facing one of the best teams in the world,” Simeone told the pre-match media conference on Tuesday. “In the last 14 games, if I’m not mistaken, they just lost one.”

“The new coach has brought solidity, teamwork, commitment. They are fourth in the league. They are intense, dynamic, brave, with great footballers all round.”

Rangnick was appointed to see the English giants through to the end of the campaign after former United striker Ole Gunnar Solskjaer was sacked as manager in November.

The German boss has presided over just one Premier League defeat, although United are still 17 points adrift of Premier League leaders and reigning champions Manchester City.

Europe offers greater prospect of success for the three-time kings of Europe, with United away to Atletico, who are themselves struggling to defend their title in LaLiga.

Midfielder Fernandes pointed to Sunday’s 4-2 win at bitter-rivals Leeds as proof that reports of dressing-room unrest under Rangnick were misplaced.

“I saw the goal of H [Harry Maguire] and I’m seeing Paul [Pogba] running behind him, sliding on his knees, happy for him,” Fernandes told a pre-match conference on Tuesday.

“So, I think honestly it’s just people trying to complain and making stories about this club because we know that when someone talk about this club or about some player of this club they go around the world with their voice. For us, it means nothing.”

And the 27-year-old Portugal international added: “Here in this club I never heard someone complain about the tactics and I hope no one does that because it’s not respectful on the coach’s ideas, because I think we have been doing so well since he arrived.

“We have more identity as a team, I think.”

Wednesday’s match takes United goalkeeper David De Gea to former club Atletico. At the other end of the pitch, Fernandes was glad the Red Devils could call on Cristiano Ronaldo’s “smell for the goal” at the Wanda Metropolitano.

No player has appeared more in the Champions League than the 37-year-old Ronaldo, who has five winners’ medals, with the former Real Madrid star long a thorn in the side of Atletico.

“Cristiano has won this competition many times,” said Fernandes of Portuguese compatriot Ronaldo.

“Everyone knows in this kind of competition he has that smell for the goal, he has that smell for doing different things.”

Fernandes, however, added: “But it is always the first time for someone that wins, so sometimes it’s about someone [getting] more experience.

“When Cristiano won the first one, he probably was not the most influential player or had more experience in that competition [than others] and he won it anyway, and he helped the team win the Champions League.”

Veteran striker Edinson Cavani will be absent for a fourth straight game, with a groin injury.

“No, Edi will not be able to make the trip,” Rangnick said at the conference.

Atletico, meanwhile, will be without their captain, Koke, who has sustained a thigh injury.

“There are other players waiting for an opportunity,” Simeone said.

Both De Gea and Ronaldo, in particular, can expect a rough reception from the Atletico crowd, with Rangnick saying: “Some of our players will not be received with a red carpet, obviously.

He added: “I don’t think that the game and the fixture will be decided [on Wednesday]. It will be decided in the second leg at Old Trafford.”
