Arsenal boss Arsene Wenger has admitted that his team will have to be on their mettle in their Premier League match against West Bromwich Albion.
The Gunners have enjoyed a strong start to the season and are currently level on points with Manchester City at the top of the table.
However, Wenger has insisted that he is taking nothing for granted ahead of his team's trip to The Hawthorns after watching the Baggies' display against Manchester United.
He is quoted as saying by BBC Sport: "I watched them against Man United and they looked a very well organised team and - as always with a Tony Pulis side - fully committed.
"On top of that they are in a difficult situation a little bit in the Premier League and you expect what you always expect in the Premier League - a committed, physical, fast game and a game where we cannot afford to make any mistakes."
Wenger's men play West Brom tomorrow.
