"Patrik, he belongs to Aston Villa and I don't want to upset Martin (O'Neill)," Redknapp told Sky Sports News.
"I think an awful lot of Martin and he could get upset very easily and I don't want to upset him!
"He belongs to Villa and unless Martin decides he doesn't want him any more, he stays at Aston Villa.
"His name was put to me by an agent who asked if I'd be interested. I said, 'yeah, I would be', but since then I think Martin wants to keep him, that's the end of the story."
