Frank Lampard played down the jeers from some Chelsea fans when he brought on Raheem Sterling and Hakim Ziyech during the 3-1 win at Bournemouth.
Lampard enjoyed a first Blues win since returning as stand-in boss, thanks to late goals from Benoit Badiashile and Joao Felix.
The travelling support also chanted abuse aimed at joint-owner Todd Boehly following the team’s disastrous season.
The win ended a run of six straight defeats.
Lampard introduced Sterling and Ziyech midway through the second half and the pair defied the hostile reception from their own fans to set up the second and third goals to seal a first Premier League win since March 11.
“Our fans were fantastic and I personally appreciate their support,” Lampard said.
“We had a moment at the end of the pitch where everyone feels good for a day.
“It is important to build a connection between the fans and the players.
“But in terms of the subs themselves they all made impacts. Ruben (Loftus-Cheek) and Raheem gave us some calmness on the ball and Raheem was then involved the third goal. Hakim came on and got an assist and played really well.
“Opinion can always change in a period but they are two players who want to do well as football players and they want to do well for Chelsea.
“There’s maybe been a bit of under-performance at times this year but I think class is permanent and I am pleased with the impact had then whey came on.”
Meanwhile, Chelsea are assessing a hamstring injury Ben Chilwell suffered during the second half.
“We don’t know how serious but with a hamstring at this stage of the season he has got to be a worry for the last four games,” Lampard said.
