Arsenal striker Pierre-Emerick Aubameyang is not happy with the club's defenders.
The star striker netted two goals to give his side a 2-0 lead away from home against Watford.
But a miserable second half display saw the Gunners concede two goals and two points, while they could have easily lost the game.
Aubameyng believes the team must tighten up defensively.
"Obviously we didn't expect that [the comeback]," the 30-year-old told Canal Plus .
"We knew that they were going to try and come back with good intentions, of the kind they demonstrated in the second half.
"Sadly, we were not able to deal with them well. I feel like we are literally giving goals to the opposition, it is up to us to progress in that respect."
