Arsenal attacker Kai Havertz has defended Aaron Ramsdale after victory over Brentford on Saturday.
Ramsdale dropped a howler to allow the Bees to level before Havertz headed a late winner for the hosts.
Havertz later said: "It was not nice to concede so close to the half-time whistle.
"But mistakes are part of the game.
"I myself made mistakes that led to goals and we showed a good mentality from the first second of the second half."
