“There are probably no words that can put into context what Mr Abramovich has done for this football club,” Terry told Chelsea magazine.
“He has obviously transformed the team but also, behind the scenes, he has done so much, not least the training ground.
“When you speak to him, he talks football. He wants to know how the club can improve and what he can do to improve it. He wants to keep pushing on.
“He wants to win every trophy, every single year. That is his target every season. And that is what he will keep here – showing us the level we are expected to be at, which we have to keep striving for.”
