Arsene Wenger has said that Blackburn Rovers will prove "a massive test" when his new-look Arsenal side travel to Ewood Park this weekend.
Blackburn have picked up just one point from four league games so far this season, but the Frenchman is taking nothing for granted after his side travelled to Dortmund in midweek.
"Blackburn is a massive test for us," he said, according to The Mirror. "If you want to play a good role in the Premier League, the way you transition from Champions League to championship is important.
"Playing away from home after a Champions League game is vital as well."
The Gunners have won just once this season, after a draw to Newcastle and two losses to Manchester United and Liverpool.
