Antonio Conte has taken a pop at Chelsea's Premier League rivals in Manchester by criticising the spending policies of Manchester United and City.
The Blues can edge closer to the title tonight if they beat Southampton, while a win would put them 14 points ahead of Pep Guardiola's fourth-placed side, who play in the Manchester derby on Thursday night.
And Conte has told the clubs headed up by Guardiola and Jose Mourinho that spending big doesn't lead to success.
"This season it's very important to understand that it's not always about who spends more money who wins," says Conte.
"This season isn't the only season both Manchester clubs have spent a lot of money. Look at the past. It's right for them to do this, to reinforce their teams, if they think this is the right way to win the title.
"But every single club decides their own strategy. This season is very important because we are trying to build something important for the present, to put the foundations down and be strong, stronger for the future."
