“Not only because of the league itself, but because of its culture and the language.
“I want to learn the language as quickly as possible in order to communicate with my team-mates better. At Atletico I used to speak with [Kieran] Trippier, but my English isn’t good enough. I don’t dare do interviews in English!
“When a team wins the Champions League, you already know how strong they are – but when you actually face them, you realise how hard they work. I want to win the Premier League and I think I am in the best team to do it.”
