The 25-year-old is already tied to a long-term contract at Tottenham, but the club are ready to offer the midfielder an improved deal after he was the subject of bids from Chelsea over the summer.
“Luka will just get on with it – the chairman will sit down and discuss his contract and make a deal,” said Redknapp.
“We are looking to make him a good offer. The transfer window being shut now makes my job easier because he has to just get on with playing.”
