Benfica midfielder Orkun Kokcu has keen admirers around Europe at present.
According to Portuguese outlet O Jogo, Manchester United are at the top of that list.
The Red Devils are very keen on bringing the 23-year-old to Old Trafford in the summer.
Benfica are not eager to sell, as they believe that Kokcu will only get better in the coming years.
He has scored three goals and managed 10 assists in his first season in the Portuguese league.
Benfica are set to demand at least 40 million if they are to sell him in the next window.
