The striker has been unable to make an impact for Spurs this season, and Redknapp has admitted that, if a suitable offer were tabled, he could let the Russian go.
"If he wanted to go and it was a good offer, then we would look at that, for sure," he said.
"He's not a player that I'm looking to move. I like him. He's a good person, good player. I hope he can have a good season."
However, Redknapp hasn't completely shut the door on him and he said that he needs to prove himself to be given an opportunity.
"He has to work hard every game," he added. "He has to be more consistent.
"He didn't have a great pre-season. He hasn't shown enough this year to be in the team."
