The demands of Cristiano Ronaldo and Bruno Fernandes in the Manchester United dressing room have emerged after the Reds made it back-to-back wins.
Fred's second-half strike proved to be the winner as they marked Ralf Rangnick's debut as interim manager with a win following the 3-2 win over Arsenal in midweek.
As a result, they have fired themselves back into European contention as their tenure under the German got off to a successful start but circumstances were a lot bleaker just weeks ago.
After Ronaldo's return to Old Trafford in the summer, there was speculation surrounding the impact he would have on the Reds dressing room, but it has emerged that he and his Portugal teammate Bruno Fernandes are the driving force behind the standards of performances.
To date, the 36-year-old has won five Ballon d'Or trophies, multiple league titles with Manchester United, Real Madrid and Juventus as well as being crowned Champions of Europe on five occasions.
His brace against Mikel Arteta's side saw him surpass 800 career goals. Fred has discussed how Ronaldo and Fernandes have improved the squad since their arrival.
"His [Ronaldo] impact was very positive," Fred told ESPN Brasil.
"It’s obvious that in the first games, it was difficult for us, we had some defeats in some big matches, but I think his impact was very positive because a quality player, as great as Cristiano, being able to share the locker room, being able to have a day-to-day life with him, is very important.
"It’s like I say, it’s hard for you to get there, but it’s even harder to keep up, and he stayed on top, he works for it. It’s an honour to be able to work with him, to be able to share the locker room."

During a dismal run of form, United were on the receiving end of heavy and demoralising defeats to rivals Liverpool and Manchester City as well as Leicester City and Watford as the catastrophic display against the Hornets spelt the end of Ole Gunnar Solskjaer as manager.
Fred revealed: "Everyone wants to have a great performance, both for themselves and the group, and if something goes wrong, we’ll demand from ourselves.
"We had some defeats, after the games, we questioned ourselves there in the dressing room, he challenged the others, Bruno [Fernandes] challenged the others, I did, I demanded from myself too, I could have done better.
"So this is normal, if the performance isn’t good, you have to have this self-criticism, for yourself as well as for others."
