Lucas Moura's agent Wagner Ribeiro says any move to Manchester United is off as they will not up their bid for the Brazilian ace.
United have lodged an offer for the Sao Paulo midfielder, currently in England with Brazil's Olympic squad.
But with Sao Paulo wanting around £30million, it appears their asking price could be too high.
Ribeiro, one of the leading agents in South America, does not think Moura will be moving anywhere this summer after United's bid was rejected.
"They have reached their limit," Ribeiro told UOL.
"Lucas Moura won't leave. He is happy at Sao Paulo. We have to forget this subject. There is no possibility he leaves now.
"Manchester United made an offer, which was rejected and they won't make another one as they have reached their limit."
