Redknapp described Modric as 'irreplaceable' and also said Gareth Bale and Sandro are not for sale at any price. The Spurs boss is looking in the transfer market to help build on his current squad as he seeks to bolster his squad for a push to claim a UEFA Champions League place next season.
The Spurs boss says he is a long way off of signing any players after being linked with Villarreal striker Giuseppe Rossi, Falcao at Porto and West Ham's Scott Parker,
Redknapp said; "It's been busy - I've been busy doing nothing really, we haven't got anywhere.
"There's been lots of phone calls, lots of talk in the newspapers but we're really not close to making any signings and certainly not looking to sell any of our better players.
"We're not selling Luka Modric, we're not selling Gareth Bale, we're not selling Sandro.
"We are looking to build a team at Tottenham, not dismantle one. If we're going to push on as a football club we need to keep them players and we need to add one or two other top players to them if we're looking to have a chance of ever getting back in the Champions League again.
"So we're not looking to sell players - that would be a massive backward step for the club."
Redknapp also laughed off suggestions that Modric could leave for £20 million this summer, he replied: "£20 million for Luka? They've got to be dreaming, he's such a fantastic player.
"You know, we've enquired about players and we're getting quoted more than that for people that couldn't lace his boots, so it's not a go-er.
"I wouldn't put a value on him, I wouldn't want to sell him. He's one of those boys every day you come into work for, and that's what it's about now.
"I come in and I see him and he's just a great guy, he trains, gets on with the job, never complains, he loves his football.
"He's the most low maintenance, easy to handle professional you've ever seen and he's a fantastic player. So he's the last player you ever want to see leave your football club - he's irreplaceable."
