Former Manchester United boss Louis van Gaal has suggested Erik ten Hag should rule out a move to the Red Devils because they are "a commercial club".
Interim boss Ralf Rangnick, who replaced Ole Gunnar Solskjaer, will be in charge until the summer.
"I'm not going to advise [Erik], he'll call me himself. But he must choose a football club and not a commercial club," said Netherlands boss Van Gaal.
Ten Hag, 52, has a contract with the reigning Dutch champions until 2023.
However, that is unlikely to prove an obstacle should United decide the Dutchman - who led Ajax to league titles in 2019 and 2021, plus the 2019 Champions League semi-finals - is the right man to replace Rangnick.
