Per lauds Gunners flexibility
Arsenal's ability to change game plans for different matches has been an important factor in their consistency this season, according to Germany defender Per Mertesacker.
The Londoners have often relied on all-out attack in the past but this term they have strengthened at the back, allowing the side to occasionally soak up pressure in defence before springing forward on lightning raids.
"We are capable of doing different things in different games and that is what makes it harder for the opponents," Mertesacker said.
"We go game by game and concentrate on having a game plan and trying to implement it. Sometimes we need to adjust."
