Filipe Luis admits he found himself questioning the professionalism of Real Madrid star Eden Hazard when they were teammates at Chelsea.

Luis left Atletico Madrid this summer to return home to Brazil at Flamengo.

And he recalled to YouTube channel '2AngryMen TV' that Hazard would be on his phone before games: "Eden played Mario Kart in the locker room.

"The fitness trainer said '10 minutes and we go out to warm up', and he wasn't even changed and kept playing."

But, without a doubt, what surprised Filipe the most was the Belgian's response: "Calm down, give me the ball, no problem..."

Luis added: "For me, concentration is the most important thing. Being with your mobile phone for a long time on Facebook, Instagram ... takes it away, especially if you are on it 5 hours a day. The player has to be with his eyes wide open."
