Chelsea and Los Che confirmed an agreement last night.
Redknapp told talkSPORT: “Chelsea have signed him? I didn’t know that. Well, I would think that’s the end of the Modric deal then, surely. I would [think the Mata deal has killed the Modric move]. I had no idea about that.
“We tried to get [Mata] to be honest with you. We were in for him strong about three weeks ago.
“I was driving back from the pre-season game with Brighton and the chairman said that he was confident he was going to sign the boy that night.
“He obviously turned it down but [the Chelsea move] has come out of the blue.”
