Tottenham boss Harry Redknapp accepts they face a massive challenge to win at Manchester City.
He wrote in The Sun: "We go to Man City having become much more consistent and durable than when they put five past us at the Lane in August.
"The only difference between us and City is that they can afford to pay players £200,000 a week.
"At the drop of a hat they can go out and buy Samir Nasri, Sergio Aguero and David Silva. No single game is going to define one of the most open title races for years but Sunday's clash will be a cracker.
"City have won all 10 Prem home games this term but it would be a fantastic achievement for us to go there and change that."
