Chelsea captain John Terry feels the club owes all it's success to owner Roman Abramovich.
Speaking with Marca, Terry says Chelsea wouldn't be where they are today without the Russian billionaire.
"Absolutely. He made a big investment in this club. He clearly loves Chelsea and has given everything to be champions of the Premier League and Champions League.
"He was sometimes frustrated by the results and we wondered why.
"What went bad with his relationship with Jose Mourinho? That was when he left, now they have a very good relationship."
