Chelsea winter signing Noni Madueke has heaped praise on recent arrival Enzo Fernandez.
The ex-Benfica central midfielder is the club's record signing, arriving on deadline day.
Fernandez is only 21, but he has already made his mark at international level by winning the World Cup with Argentina.
Asked about Enzo, winger Madueke told the club's 5th Stand app: "He is going to bring a winning mentality to the team, which I think is priceless.
I can't wait to meet him, and get on the pitch with him!"
He added: "I watched him play at the World Cup and he has such top qualities.
He is a great player, and obviously he has proven that he is a born winner by lifting the World Cup."
