Jose Mourinho has risked opening up old wounds with Cristiano Ronaldo after labelling him as the reason for his failure to win the Champions League at Real Madrid.
The Chelsea boss spent three years managing Real Madrid between 2010 and 2013 before eventually leaving for Stamford Bridge. He was brought in from Inter Milan to secure La Decima, but ultimately failed.
He came closest in 2012 when Los Blancos got to the semi-final before being knocked out by Bayern Munich on penalties. Ronaldo missed the decisive spot kick and Mourinho has not forgotten.
"Winning the Champions twice as coach has made my career a special one," Mourinho, who lifted the Champions League with Porto and Inter Milan, told TVI24.
"I've been in several semi-finals too and some defeats were especially hard to take, such as the goal that did not exist against Liverpool [during his first Chelsea spell in 2005 or on penalties in 2012 when our first-choice penalty taker [Ronaldo] went up first and failed."
Bayern Munich famously went on to lose to Chelsea in the final in similar circumstances.
The new quotes could have grave consequences for Chelsea, who had been labelled as frontrunners to bag Ronaldo's signature in a £60 million deal if he departs the Bernabeu. Ronaldo is reportedly unhappy at Real Madrid after the sale of Xabi Alonso and Angel Di Maria and could push for a move away.
Ronaldo, who earns £290,000-a-week at Real Madrid, has also been linked with Manchester City and Manchester United. For obvious reasons, Manchester United are considered favourites to bring Ronaldo back to Old Trafford, but Chelsea did have an upper hand.
Mourinho had a tense relationship with Ronaldo at Real Madrid but they seemed to part on amicable terms after the Chelsea boss claimed working with his compatriot was the "highlight of my career". Both the Portuguese men are represented by super agent Jorge Mendes as well, which could have given the Blues the upper hand in negotiations.
However, it remains a fact that Ronaldo has a close connection with Manchester United and the Old Trafford faithful. The 29-year-old recently reiterated his love for the club and admitted a desire to return there in the near future.
Having seen Mourinho pin the blame for Real Madrid's 2012 failure in the Champions League, it may have made his decision that bit easier.
