The Spanish goalkeeper, who was hand-picked by the great Sir Alex Ferguson, departed Old Trafford in 2023 after failing to agree terms on a new contract.
The 33-year-old, who had spent 12 years of his career, at the club but was replaced by Inter Milan’s Andre Onana in a £47m deal.
Mail Sport reported Newcastle had been considering a shock move for De Gea, who has also been linked with clubs in Saudi Arabia.
But he has so far remained a free agent and provides an experienced option for teams in need of a top goalkeeper.
The January transfer window offers clubs in desperate need of reinforcements the chance to pick up a bargain with him.
