Despite being a serious challenger for a top-four position and reaching the second round of the Champions League, Tottenham are one of the clubs who refuse to pay their players over £100,000 a week.

Manchester City's Yaya Toure reportedly earns £250,000 a week while Tottenham's top earners take home around a third of that amount.

Leeds were one club who smashed their wage structure to attract the likes of Rio Ferdinand and Robbie Keane a decade ago as they chased European glory.

But just three years after reaching the Champions League semi-final, the Yorkshire club were relegated to the second tier of English football, having been forced to sell the majority of their well-paid stars.

Redknapp has had to shelve bids for Luis Fabiano and Diego Forlan due to their salary demands this month but insists that offering stratospheric wages would have a similar effect on his club.

"I wouldn't want the chairman to start paying £130-140,000 a week for a player," Redknapp said.

"It would be difficult when you've got players here getting what they get who are probably better than the ones you've got to pay that money for.

"So, suddenly, the whole thing would get out of hand, wouldn't it?"

Redknapp takes his side to Fulham tomorrow looking to book a place in the fifth round of the FA Cup.

The 63-year-old won the competition with Portsmouth in 2008 and reached the semi-finals last year with Spurs before being eliminated by his former employers.

Redknapp handed a number of his fringe players a start in the third-round win over Charlton earlier this month but intends to field his strongest XI at Craven Cottage against the team that Spurs knocked out at the quarter-final stage last year.

"We want to go there and get through if we can," Redknapp said.

"I will field my best available team. Benoit (Assou-Ekotto) is fine after his knee injury. (Heurelho) Gomes will go out there. Hopefully he will be okay after his shoulder injury.

"It is a big game. We want to get through and give it our best shot."

Roman Pavlyuchenko is likely to start on the bench, with Redknapp expected to start with either Peter Crouch or Jermain Defoe alongside Rafael van der Vaart up front.

The Russian claimed earlier this week that he could leave White Hart Lane after falling down the pecking order but Redknapp insists the club have had no bids for the striker and insists he is not for sale.

He said: "No one's come in for him. He's here and I wouldn't think there is any chance of him going before Monday.

"There's nothing happening at all with Pav."

Fulham boss Mark Hughes was under pressure around the festive period after a run of poor form plunged his side into the relegation zone.

The Welshman has overseen an upturn in form recently, with Fulham having lost just once since Tottenham beat them on New Year's Day.

Tottenham beat Fulham away in October too but Redknapp admits he is expecting a difficult clash against their west London rivals.

"It'll be a tough game on Sunday," he said.

"I've never played Fulham yet and not had a difficult game.

"Mark's got them playing well. We were fortunate to take six points off them this year in all honesty.

"We had two very tight games and we came out in top on both games, but both of them were very close."

One player who Redknapp will have to without is winger Gareth Bale, who has been ruled out with a back injury.

"Bale's seen specialists, needs a bit of work on it and he will be okay," Redknapp said.

"He doesn't need an operation - that's the last resort. It was a little back injury that went into spasm."
