Any deal between Manchester United and Sao Paulo for Lucas won't be finalised until after the London Olympics.

The Brazil international's agent Wagner Ribeiro is in England to meet with United officials on behalf of both Lucas and Sao Paulo.

"I do not want to unsettle Lucas. He has his mind focused on the Selecao, and never participated in any negotiations," said Ribeiro.

"There has to be discussions then later a decision will be made."
