Chelsea boss Jose Mourinho had a dig at Arsenal coach Arsene Wenger while being interviewed ahead of the Blues’ clash against Manchester City on Sunday.
When asked if he was surprised that City boss Manuel Pellegrini had signed a new deal after failing to defend the league title last season, Mourinho replied in his typical ‘take no prisoners’ way.
"Why? Some other clubs, they have disappointed for 15 years and the manager is the same."
The last time that Arsenal won the league was in the 2003/04 season under Wenger.
The Chelsea boss and his Arsenal counterpart have for years been directing verbal attacks at each other. In February Mourinho called Wenger "a specialist in failure" while Wenger labelled the Blues coach as being "disrespectful".
The Frenchman did however have the last laugh recently when Arsenal beat Chelsea in the Community Shield handing Wenger his first win against his rival in 14 attempts.
Mourinho says Sunday's game against Manchester City is not too significant as it is very early in the season and there is still a lot of football to be played.
Chelsea kicked their off league defence with a draw against Swansea while City beat West Brom in their opener.
"I cannot say it's crucial, it's decisive, or it's very, very important," said Mourinho.
"But it is two title contenders, and three points."
In the 2013/14 season City were the league champions but finished eight points behind Chelsea last season.
Mourinho said that the significance of Sunday’s game meant nothing this early in the campaign.
"The season is very long. Thirty-eight matches is an eternity, a marathon which started last week and ends in around 10 months," he added.
"If you can get three points and your opponent zero it is important.
"But for sure I am not going to say the game decides anything for the winner or anything for the loser."
