Roberto Di Matteo led his men to an unlikely victory on penalties against Bayern Munich in the German giants' own back yard and their inaugural European trophy has been praised further with the honorary title.
The Blues were handed the award on Monday from their respective peers at the third annual ECA Awards at the Association's General Assembly in Geneva, Switzerland.

Nevertheless, the club were "recognised for their outstanding achievement during the 2011-12 season on a European and domestic level," according to a statement.
Chelsea are one of the teams that makes up the ECA, the independent body that replaced its predecessor - the G14 Group and the European Club Forum - when both were dissolved in 2008.
The first ECA awards were introduced in 2010, designed with the aim of "rewarding outstanding club performances, encouraging best practice and highlighting successful club management".
The award represents yet more good news for the Blues, whose double last season has been followed up by a perfect start to this season's Premier League campaign.
And, despite a disappointing 4-1 loss to last season's Europa League winners Atletico Madrid in the European Super Cup, plenty of early-season optimism around the club will only be reinforced with this latest achievement.
