Match-going Chelsea fans have never been particularly supportive of Mauricio Pochettino and it showed against Leicester on Sunday.
The fans started chanting 'You don't know what you're doing' when the Argentine took off Mudryk first, not Sterling.
After the game, Pochettino used the matchday programme as a prop to explain his team's poor performances this season.
"Look at the programme here. You see the squad, under-18, under-18, under-18, under-21, under-21, under-21," he said, pointing to the names of Ollie Harrison, Deivid Washington and Joshua Acheampong, who made the squad against Leicester.
"The squad is long because we have too many injured players, and we should use the kids.
"I really believe in our fans, in the club, in the staff that we have today and our players. Young, but no doubt we will succeed together."
