Chelsea manager Roberto Di Matteo has been quick to play down his side's unbeaten start to the season.

The Blues are currently four points clear at the top of the Premier League table and avoided defeat again on Saturday when they beat London rivals Tottenham Hotspur 4-2 at White Hart Lane.

However, Di Matteo has insisted that his players will have their record seriously challenged at some point during the campaign.

"It's early days, only eight games, and there are 30 more games to play," the Italian told talkSPORT.

"We are in good shape, we are playing some great football, scoring plenty of goals and creating more chances as well. But there will be moments where we are going to be tested more and we will see how we react to that."

Chelsea return to Champions League action on Tuesday when they travel to Ukraine to take on Shakhtar Donetsk.
