The 28-year-old arrived from Anzhi Makhachkala for a club-record fee on transfer deadline day, penning a four-and-a-half year deal at Loftus Road. However, Redknapp has revealed QPR were offered more than what they forked out for Samba by another Russian club last week ahead of the end of their own transfer window.
"We had an offer for Samba, right on the deadline and the chairman turned it down," Redknapp said after Saturday's 2-1 win at Southampton. "We had an offer of more money than what we paid for Samba. The chairman had a massive offer for him to go back to Russia."
He added: "The chairman asked me 'what do you think?' and I said 'it is up to you, it is your club, it is your decision'. I would have had no problem. I left it to the chairman. He came back and said he had turned it down and said 'get on with it'.
"The player probably spoke to the chairman but it was really important we kept him. It was really good for us. Had we had lost him, I would say that is football. He is a proper player.
"When he was sold, I could never understand why Arsenal did not sign him that time. He is everything you need. He is quick, he can play round his feet. He is a proper centre-half. He could play anywhere in this country and for all the top teams."
Samba was a behemoth at the back at Southampton as QPR eked out just their third Barclays Premier League win of the season.
"This gives us a chance, that's all," Redknapp said. "It is a chance and it keeps us in there. You could not have afforded to be cut adrift anymore. It was three big points which keeps us going.
"We needed a result at 1-1, we were playing with one up and I decided to push two up to really go for it with Loic Remy through the middle with Jay Bothroyd. We were 4-4-2, got the goal and I reverted back to 4-5-1.
"You start to look at the run of games, which ones you will win, which ones you will lose and whoever knows in football. You look at it and think we will beat them and then you go and lose. Then you think we will get beaten there and go and win, like we did at Chelsea."
