Keane is currently on loan at Celtic from Tottenham until the end of the season.
“Getting him to extend his stay isn’t something that has crossed my mind,” said Mowbray. “But we’ll wait and see. That’s not to say no.
“I don’t know what Robbie’s thoughts are on his football career. He’s a young guy still, he’s contracted to Tottenham Hotspur in the English Premier League. I don’t know what he thinks about his future.
“In the short term, he’s here until the end of the season and hopefully he’s got a few more days like today, when he makes the difference.”
