Manchester United's summer signings have shown quality and leadership in the dressing room.
That is the view of Brazilian midfielder Fred, who is having one of his most productive seasons for the club.
Fred scored the third in a 3-1 come from behind FA Cup fifth round win over West Ham United on Wednesday.
"We bring in players with good mentality, now the players that were here before change mentality as well," he said post-game.
"Erik ten Hag brings a lot of things with him, he brings energy into the dressing room. I don't know what's different, it's the same players, but a different mentality.
"Every moment we believe, we believe in the game, we have the mentality, it's important to keep this to win the trophies."
"I love to play with Casemiro," added Fred.
"He won a lot of trophies in Real Madrid, he has a good mentality in the national team as well, he's important to be a part of our squad.
"He's a big leader, he talks a lot with us, with every player, every day. He tries to work on his English as well. He is a good guy, everyone knows this, he has a good way in the dressing room."
