Manchester United goalkeeper David de Gea has hailed fellow Spaniards Juan Mata and Ander Herrera.
The trio were unable to inspire the Reds to victory against Chelsea on Saturday.
But De Gea told MUTV: "We all get on very well, both on and off the field, and I think that can have an influence in making the team play better.
"For example, when Juan and Ander are both playing, they have a great understanding on the field and that really helps. They know each other really well, from way back with the various youth levels of the national team.
"I think they have been combining superbly and they can achieve great things at this club. We're really good mates and it's marvellous to have them all here."
