“I am looking forward to playing in the Premier League, of course.
"It’s a big challenge as I consider this to be one of the two best and biggest leagues in the world, with our league in Spain, and I think it’s a dream for every player to come here and play in the Premier League, so I’m looking forward to getting started.”
Roberto, who has played more than 300 senior matches, is a former Europa League winner with Atletico and a three-time Greek league winner with Olympiacos.

Roberto, who arrives at the London Stadium with Champions League experience, made just six appearances for Espanyol last season.
