The Mirror says Keane is poised for another Premier League loan move - with a return to Aston Villa on the cards.
Republic of Ireland boss Giovanni Trapattoni reckons he would benefit from a move in the January window.
"Robbie spoke to me about this situation, after last month's game in the Faroes," said Trapattoni.
"If he has this opportunity, it's his decision. He has to make up his own mind.
"But in life it's very important to have new challenges and if it suits him, it'll be an injection for him."
