Thibaut Courtois admits he cannot pick which title is more special after holding the Premier League aloft.
The Belgian goalkeeper helped Atletico Madrid clinch the Spanish title last season while on loan last season and has added to that by playing a key role in the Blues' English premiership this term.
"It is difficult to compare. I think at Chelsea when you start the season, the objective is to win the league," the 23-year old told Sky Sports.
"In Atletico we didn't have the objective so it was maybe more special then because it was more of a surprise. But this one is very good because the Premier League is hard to win with all the top teams that are here."
