Manager David Moyes says West Ham never came close to re-signing Jesse Lingard over the summer.
Lingard, 28, scored nine goals in 16 matches during a successful loan spell at the Hammers last season.
Speculation linked the club with a permanent deal, but Moyes says Red Devils boss Ole Gunnar Solskjaer had no intention of selling the winger.
"Ole made it quite clear to me early in the transfer window that he wanted to keep him," said Moyes.
"So I knew pretty early that he would be staying at Manchester United.
"I was hearing all the stuff but I had a private conversation with Ole who made it clear he was staying.
