Eriksson, who gave Hargreaves his England debut in 2001, has been impressed by the midfielder in the clips and is ready to add him to his Leicester revolution.
"I saw his videos and if he wants to come here I will open the door and stand and wait for him in the door," said Eriksson.
"He's been very unlucky in recent years but if he's close to what he was he is a fantastic football player.
"I haven't spoken to him for a while, maybe I should.
"It's difficult to know what he wants to do when he's been away for a long time."
