Antonio Conte's substitution of Willian was booed, but the Italian's selection of Olivier Giroud paid off superbly in the FA Cup semi-final.
Olivier Giroud's wonderful goal and an Alvaro Morata header earned Chelsea a 2-0 win against Southampton on Sunday and a return to the FA Cup final.
Antonio Conte selected Giroud over Morata in attack and the France forward rewarded that faith with the opening goal in the first minute of the second half.
Cesc Fabregas and Eden Hazard combined superbly to find Giroud in the box but he still had a lot to do, jinking away from a series of challenges before prodding past Alex McCarthy.
