Redknapp: Tottenham transformed since Man City humiliation
Since then, Spurs have gone from strength to strength, thanks largely to the arrivals of Scott Parker and Emmanuel Adebayor as well as their ability to keep hold of Luka Modric in the face of interest from Chelsea.
"We're a different team," Redknapp said. "I didn't have a midfield player then, really.
"Suddenly I was throwing Jake (Livermore) in and playing him in there with Niko Kranjcar, who never played central midfield in his life before.
"It opens the barn door.
"I just felt after two or three weeks, I could see what was coming.
"I never went home and worried about it because I was confident.
"We had Adebayor coming in, we had Scott Parker. We had Sandro coming back.
"I knew we'd suddenly be a much better team."
