The agent of Porto midfielder Danilo Pereira admits transfer interest isn't a surprise.

Danilo has been linked with Manchester City, Manchester United and Arsenal just in the past week in the English press.

Agent Bruno Meirelles told O Jogo: "He's having a good season and it's only natural that he has eyes on him, but we're not worried.

"He's happy at FC Porto.

"He's enjoying his role under (coach) Sergio Conceicao. We're now seeing the best of Danilo more and more. He's getting more and more comfortable. And Danilo has grown up as a player. A lot of people were unaware of this offensive ability, but he can give FC Porto a lot."
