Jose Mourinho has revealed that re-joining Chelsea in 2013 is one of the two major regrets of his managerial career.
The Portuguese manager opted to leave Real Madrid after three years and take up a second stint at Stamford Bridge, where he won a third Premier League trophy in 2015 but was sacked seven months later in acrimonious circumstances.
Chelsea were languishing in 16th place in December 2015, just one point ahead of the relegation places, and had lost nine of their 16 previous matches.
His career has taken him to Manchester United, Tottenham, and Fenerbahce among others, but staying with Roma after they lost the 2023 Europa League final to Sevilla in Budapest ranks as his other great regret.
