Following Arsenal's 2-0 victory over Borussia Dortmund, Per Mertesacker has pushed his team-mates to replicate their Champions League form on the domestic front as they prepare to face West Brom on Saturday afternoon.
Goals from Yaya Sanogo and Alexis Sanchez secured safe passage to the knockout stages with a game to play against a prolific Dortmund side, but their focus has firmly switched to the weekend with a must win fixture looming for Arsene Wenger's men.
The Gunners currently sit eighth after last weekend's defeat against Manchester United and after losing two league games on the bounce, the pressure is firmly on Wenger.
“Saturday is a good chance to show to everyone that we are still alive"
His side eased some of that tension last night, but Mertesacker knows a good performance at the Hawthorns is essential if they are to keep their Premier League season alive.
He told reporters: "We were very convincing against Dortmund. Everyone had to learn. 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 to everyone that we are still alive. Champions League football (in the knockout stages) we have secured 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 league.”
They will have to try and get the three points without the likes of Jack Wilshere, who will miss the next three months after damaging ankle ligaments, whilst captain Mikel Arteta will also sit the game out after limping off last night.
The good news for Wenger is that Olivier Giroud is pushing for a starting berth after recovering from a broken leg, whilst Wojciech Szczesny is also set to return for Arsenal.
