Lucas Moura's agent has reiterated that Manchester United are keen to land the Sao Paulo midfielder.
The 19-year-old is widely acknowledged as one of the best prospects in Brazil, and he already has more than 10 caps for the senior team to his name.
United and Bayern Munich were linked last summer, with his agent Wagner Ribeiro claiming the pair made contact. He also revealed Inter Milan had interest rebuffed in January.
Now Ribeiro has stated once again that United are in contact, whilst also saying Inter are still keen - but he also revealed that Chelsea have joined the chase.
"I have to say that Inter, Chelsea and Manchester United have already been in contact with me about him," Ribeiro told Globo Esporte.
"He has the perfect profile to play in Europe - he's a good player, very rapid and he knows how to shoot.
"However, a possible move doesn't depend on me. You firstly have to speak with the club and then the player.
"At the moment the player wants to stay at Sao Paulo and the club don't want to sell him."
