Former Arsenal defender Martin Keown blames Chelsea attacker Kai Havertz for Gabriel Magalhaes' winner on Sunday.

The Gunners picked up the three points at Stamford Bridge as they claimed the London bragging rights courtesy of Gabriel, who tapped home a corner in front of the away fans. The Blues defence allowed Bukayo Saka's delivery to slip through to the Brazilian, who couldn't miss.

Havertz's role in the goal has been highlighted with the German accused of not doing enough.

Keown said on BT Sport: "Kai Havertz has got to do better there. He swings a lazy leg at that."

Former Fulham manager Scott Parker also added: "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]."
