Stoke City boss Tony Pulis says Arsenal striker Robin van Persie was the difference after yesterday's defeat.
For Stoke, it meant a third loss of the season, all of which have come after a Europa League outing on the previous Thursday.
"Van Persie has come on and changed the game," said manager Pulis.
"We looked comfortable until he came on, I don't think Asmir had had a shot to save up until then.
"The lads worked hard. We've lost three games this season all on the back of Europa games, but if you look at our running stats they aren't far off when we've been winning games."
