Arsenal striker Gabriel Jesus has scoffed at critics of Manchester United midfielder Casemiro.

Casemiro scored the only goal in Brazil's victory over Switzerland on Monday, which assured the South Americans of a place in the knock-out stage of the World Cup with a match to spare.

The midfielder has largely earned plaudits for his defensive instincts, but Gabriel Jesus insisted the Manchester United star 30-year-old has repeatedly demonstrated his all-around game.

"I don't know if people in England watched Casemiro's career before he came to the Premier League, but I followed him for years at Real Madrid and know how many goals he scored in the Champions League," Gabriel Jesus said.

"If you go to Google and watch Casemiro's games for Real, you will find what he is all about. He went there and scored a lot.

"I have played with some good midfielders and I put Fernandinho in there as well. But I have spent a lot of time with Casemiro and he is just an amazing player.

"Some people don't understand that and don't give him a lot of respect. But I do because I played with him for such a long time and know how good he is."

Gabriel Jesus is adamant he will prove to be a success as he is a "winner".

"He will definitely be a good signing for United because of his quality and the way he works. It is just amazing. He is just so focused all the time," Gabriel Jesus continued.

"He's like 'don't lose, don't give the ball away'. It has been the same everywhere he's been – that's why he has been so successful. If you are a player who loves to work and wants to follow a winner, then he is a great influence."
