Alan Shearer and Ian Wright have both scolded Chelsea winger Callum Hudson-Odoi for his performance in the club's 1-1 draw against Brighton.
The Blues once again paid the price for looking off their game, with Adam Webster's headed equaliser cancelling out Hakim Ziyech's opener.
Thomas Tuchel - whose side still trail Premier League leaders Manchester City by 12 points having also played a game more - blamed tiredness for their display.
But former striker Shearer said Hudson-Odoi lacked energy and that Tuchel must now arrest their worry slide, while fellow ex-forward Wright was left aghast at one piece of play which saw the 21-year-old kill the momentum in a promising attack by passing the ball all the way back to the defence.
