Arsenal's hopes of winning the Premier League suffered a fresh setback on Saturday after a 2-1 defeat at promoted Stoke.
This has provoked Stoke City stopper Thomas Sorensen into claiming The Gunners lack the stomach for a fight.
"I think with the way the other teams are playing, it's going to be really hard for them," said Sorensen in The Sun.
"They are a fantastic football side, but they are just lacking that bit of physicality.
"They want to play all the time and sometimes you have to work hard and earn that opportunity to play your football.
"I've played against Arsenal a lot of times and I expected much more of them.
"They have their excellent players, like Cesc Fabregas. But they didn't find the fifth gear they normally do.
"Once we got the second goal it felt like we were cruising. They totally lost belief. I think they expected a bit of an easier ride and no one's going to get that here."
