Manchester United remain keen to sign Shakhtar Donetsk playmaker Douglas Costa, according to the player's agent.
Costa was one of the star turns for Shakhtar as they made the quarter-finals of the Champions League for the first time - ultimately losing 6-1 on aggregate to Barcelona - and has become an integral member of Mircea Lucescu’s side since moving to Donetsk last year.
According to FourFourTwo, United attempted to bring the the 20-year-old to Old Trafford prior to his transfer to Shakhtar, and Costa's agent has revealed Sir Alex Ferguson is still interested in his client.
"At Manchester United, they have liked him for a long time,” Cesar Bottega told calciomercatoweb.it.
“Napoli are also interested.
"If an interesting offer is made, then his club will consider it. But it will have to be an important one to convince them to sell as he is a major player for them."
Whether or not United make a summer move for the Brazilian remains to be seen, but Ferguson is expected to invest substantially in his squad during the transfer window.
The United boss failed to spend a penny during January, but will have to delve into his transfer reserves in order to sign a replacement for Edwin Van der Sar, who will leave Old Trafford at the end of the season.
Atletico Madrid goalkeeper David De Gea appears to be the favourite to succeed the 40-year-old, and United a reportedly close to completing a deal in the region of £20 million for the young Spaniard.
