Mertesacker eager to make amends

Arsenal vice-captain Per Mertesacker has warned Chelsea the Gunners are ready to “try new things” when they head to the Barclays Premier League leaders on Sunday boosted by their European success.

Arsene Wenger’s 18th anniversary was marked in style with a hat-trick from England forward Danny Welbeck as Galatasaray were taken apart 4-1 at the Emirates Stadium, during which there was a first-half stoppage for flares thrown by the away fans to be cleared off the pitch and could lead to sanctions from UEFA.
