Redknapp wrote in the Daily Mail: "f I am honest, at the start of the year, I don't think you could see an English team winning the Champions League. You looked at Manchester United and thought they might go close. They were unlucky against Real Madrid - the referee's decision to send off Nani cost them.
"It has been one of those years for English clubs in the Champions League. We've not got a single club in the quarter-finals, but I'm sure next year will be different.
"I think we will probably see a stronger Chelsea and a stronger Manchester City. The Barclays Premier League is exciting, it is probably the most exciting league in the world. But in terms of actual football, I think the Spanish league takes some beating."
