Martin Keown and Scott Parker blamed Chelsea forward Kai Havertz for Chelsea’s 1-0 defeat to Arsenal on Sunday at Stamford Bridge.
Chelsea failed to deal with Bukayo Saka’s innocuous corner to allow Gabriel to poke home a second-half winner at Stamford Bridge.
Havertz was guarding the near-post as the corner came in but failed to clear the ball before it also flew past Thiago Silva and Edouard Mendy to be met by Gabriel.
Speaking about the goal Chelsea conceded to Arsenal, Parker told BT Sport: “You’re always massively disappointed when you concede from a set-piece.
“Arsenal are certainly good at scoring set-piece goals and that’s something we prepped for [before Fulham’s 2-1 defeat at the Emirates in August].
“I don’t know why Havertz has gone so far forward before the corner. If he goes deeper he can come on to it, instead he starts high and then starts running back and then he’s got a lot to deal with.”
Arsenal legend Keown added: “Kai Havertz has got to do better there. He swings a lazy leg at that.”
