Stoke City midfielder Steven N'Zonzi believes Arsenal's players need to toughen up if they are to mount a serious Premier League title challenge.
The Gunners' suffered an untimely 1-0 defeat against the Potters on Saturday - a result that seriously dents their hopes of winning the title.
And N'Zonzi believes that one of Arsenal's major weaknesses is their inability to cope with physical pressure against some of the less technical teams in the division.
"We know that Arsenal play good football but, when you start kicking them a little bit, it gets harder for them," N'Zonzi was quoted as saying by Goal.com.
"They don't like it, we know that. We don't care. We'll keep on doing it, being strong and trying to be as good as we can be on the ball.
"It's not a surprise they have been moaning because they have plenty of technical players."
And when asked whether Arsene Wenger's men needed to display more resilience, the 25-year-old Frenchman added: "Yes - this is how Premier League football is. It's really good, it's really strong."
This is not the first time that Arsenal have been accused of being mentally or physically weak during Wenger's tenure.
And it's not the first time either that Stoke City and Arsenal have come to blows over their differences in playing style.
The Gunners, meanwhile, now find themselves four points behind league-leaders Chelsea with 10 matches left to play.
