Arsenal manager Arsene Wenger has called for focus when his side travel to Stoke City on Sunday.
Both sides recorded draws on the opening day, and Wenger doesn't expect Tony Pulis's side to give him an easy ride as they look for their first win of the season.
"They are teams who have experience of the Premier League who know how to make life difficult for you, who have specific style that is always difficult to face," said the veteran manager.
"They are a team who defends very well, and their football is based on efficiency and that always demands a great concentration level."
Wenger will be without duo Robin van Persie and Alex Song for the match after they joined Manchester United and Barcelona respectively in the past week.
