Rafael da Silva's agent, Cassiano Pereira, has stated that there is little chance his client will move to Brazil, according to Brazilian newspaper Lance.
The 23-year-old was linked yesterday with an end of season move back to his native country to join Corinthians.
The South American outfit are looking to replace the retiring Alessandro and see Rafael as the ideal purchase, but the United youngster's agent has played down speculation.
Pereira has stated that his client remains happy in Manchester and, despite the fact that a move to Corinthians is an appealing prospect, there will be no negotiations taking place.
"Nobody told me nothing of the Corinthians. Suddenly, it is in their interest," the agent said.
"If there is, it's great. All entrepreneurs and players see the Corinthians with great eyes. But it's hard, because he is happy at United."
Rafael arrived at Old Trafford with his brother Fabio in 2008 and has managed to stake a massive claim for the right-back berth over the last few seasons.
However with the likes of Chris Smalling and the recently acquired Guillermo Varela vying for the full-back positions, Moyes may be tempted into a transfer if Corinthians were to place a substantial offer.
United fans will surely be hoping they can keep hold of a player who they have developed themselves, and if Rafael's agent is to be believed, the player himself wishes to remain in the Premier League.
