Traveling fans chanted”we want Sarri out” and”you do not understand what you are doing” after struggling Cardiff took the lead from the Premier League match.
Late goals by Cesar Azpilicueta and Ruben Loftus-Cheek saw lack-lustre Chelsea result from behind to win 21.
“They’re probably unhappy for the result,” explained Sarri afterwards.
“I could understand, I could understand very well. I’m getting used for this.”
Italian Sarri was already under pressure before the Cardiff game, with a streak of four beats out of five away league games and fans becoming frustrated with the individual kind of football known as’Sarriball’.
Moreover, Sarri’s decision to leave important scorer Eden Hazard and also midfielder N’Golo Kante out of the starting line-up proved unpopular with Chelsea fans.
“In the past week that they played with two games to get their national teams for 180 minutes therefore that I presumed it was time for you to break them.
“We were lucky because we gained three things and Hazard played with 30 or 35 minutes and Kante zero moments .”
“We didn’t play well in the first half and we surrendered a stupid goal,” added Sarri on his side’s performance in Wales.
“In the end we all deserved to win.”
