Wagner Ribeiro, one of the leading agents in South America, does not think Lucas 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."
