"I was living this atmosphere in London. And on Friday I went to Buckingham Palace like a normal person, because I am a normal person! I did it with a hat to live this situation because I think for sure we will remember this for the rest of our lives.
"I want to give condolences from me, from the club, from the players to the Royal family. Then football has to go ahead and we will do it, but I think the Premier League made an important decision to stop football and show respect for the death of the Queen.
"We are talking about a situation that will find it in the story of the future. To stay here in this moment and to live this moment here is for sure a sad moment, but at the same time it is a special moment because we are talking about the death of the Queen.
