Jose Mourinho said Chelsea's win at Crystal Palace on Saturday showed it has the character to maintain its Premier League title challenge.

The Chelsea manager was heavily critical of his team when it lost at Selhurst Park last season and when asked what his players lacked in the game, wrote the word "balls" in a reporter's notebook.

Seven months on, Mourinho was asked what had been the key to his side's 2-1 victory and this time wrote "big balls" in the same reporter's notebook.
