Chelsea manager Jose Mourinho has urged John Terry to improve his performances next season and extend his record as the Premier League's all-time top scoring defender.

The 34-year-old was an everpresent in the Blues' Premier League title triumph last season and defied detractors that suggested his ageing legs would not be able to make such a stellar contribution to the club's cause.

However, similar concerns are expected to be raised in regards to the west Londoners' skipper during the forthcoming campaign, despite his recent exploits.

And Mourinho is adamant that Terry has felt the full benefit of being protected in other competitions in order to focus on the domestic division and urged the centre back to continue to build on his impressive displays.

"Obviously last year he was fantastic. He didn’t play in the national team and when I could protect him in Capital One Cup and Champions League matches, I did," said the Portuguese boss.

"We invested everything into the Premier League with John, so let’s see if he can have the same season, with one more goal scored, to be better than this season," said Mourinho.

Terry has scored a total of 39 goals in England's top flight, a tally that cannot be matched by any defender in Premier League history, but Mourinho has also hinted that it is not only the veteran defender that contributes to his imperious displays on the pitch.

He added: "It’s not just to him; it’s to me and to my assistants and to my medical department and the ones that work on the prevention of injury and the ones that work on the recovery of injuries.

"It’s up to all of us, not just John. We all have to improve. If we want to be better, we have to be better ourselves," the Portuguese tactician explained.
