Cape Town - Per Mertesacker has called on Arsenal to turn their English Premiership form around against West Bromwich Albion on Saturday.
The Gunners go into the game on the back of two domestic defeats, although they got back to winning ways against Borussia Dortmund on Wednesday night.
Mertesacker says the result came at the ideal time, but insists the team must build on it when they travel to the Hawthorns.
“We were very convincing [against Dortmund],” he told the Arsenal Player.
“We have to show character and that is what makes me really happy for the next few games, because we have to sharpen up in the Premier League as well.
“Saturday is a good chance to show everyone that we are still alive. We have secured Champions League [last-16] football and that gives us a life, but that has nothing to do with the Premier League.
“Dortmund are a good example of that, because they are already through but they have suffered a lot in the [German] league. We have to come back in the Premier League and that is the next target.”
West Bromwich Albion host Arsenal at The Hawthorns on Saturday at 14:45.
