He was subsequently named Man of the Match.
Ivanovic was also outstanding during the title-winning campaign of 2014–15 and played in every minute of the 38 games.
The Blues boasted the best defensive record in the league and he was one of six Chelsea players named in the Team of the Season.
He ended his Chelsea career with a goal against Brentford in his final game.

Eden Hazard scored a magnificent solo goal in the 8th minute of second half.
