Chelsea midfielder Frank Lampard believes Harry Redknapp has turned Tottenham into a powerful side capable of breaking the top-four domination of the Barclays Premier League.
Redknapp is uncle to the England midfielder and saw the Chelsea star grow up at West Ham and has compared Lampard's desire to perfect his game at an early age to that of golf star Tiger Woods.
But the mutual appreciation is clear as Lampard assessed Redknapp's Spurs team ahead of Sunday's visit to Stamford Bridge, saying: "Harry saw me grow up so he knows the work I put in at a young age. He saw that as a big talent of mine, to work hard as a kid, and I respect Harry highly so it is very nice when he says things like that."
He added: "Harry has put together good sides time and time again, at all the clubs he has been at and it was about time he got a club that had the resources to push for the top four.
"Tottenham have spent very well. When Harry joined them they were near the bottom of the table and now they are a very powerful side with great attacking options. They have a possibility of challenging for the top four.
"With Peter Crouch they can play more direct because they do have that option and no-one can live with him in the air if the ball is in the right area.
"I saw Spurs play against Manchester United and they did end up playing quite a few long balls into Crouchy - but they have the players that are very sharp around him to feed off it."
Chelsea managed just one point against Spurs last season and the north Londoners are the last team to have beaten the Blues, so there is no chance of the game being taken lightly.
"We beat them so many times over so many years and in a derby it shouldn't be like that, so they have given us tougher games recently because they were so hell bent on getting results against us," added Lampard.
"They are strong and a derby atmosphere always makes it harder to beat them. We will have to be at the top of our game if we are going to beat them."
