Redknapp knows that he would be leaving a club that he has brought on considerably over the last few years, with the help of a number of star players like Gareth Bale, Luka Modric and Rafael van der Vaart.
"This is a club that is going forward," Redknapp said. "It's been a great club for many years. It won the double in the 1960s.
"It's all in place again now. There is a new training ground coming, a new stadium coming. It's a club with fantastic potential.
"We've established ourselves as a top-six team and we are trying to get established as a top-four team, which is hard as there are six teams there who are all very strong."
