Asked about comparisons with Eden, he told France Football: "It's been a while since someone asked me so many questions about him.
"It was mostly when I was at Lens training center and Belgium. Now I am on my own.
"He's happy for me. He told me I'm hot! But I have to continue like this. We hope we will meet in the national team to play together. He does not specifically give me advice. He has his career to manage. We're two different players in two different clubs, he does not break my head saying: 'Do this, do that'."
