Arsenal maintained their recent impressive form as they overcame a stubborn West Brom 2-0 at the Emirates on Monday night, courtesy of an Alexandre Lacazette double.
Gunners boss Arsene Wenger made two changes from the 0-0 draw with Chelsea, with Mohamed Elneny and Alexis Sanchez coming in for the injured Danny Welbeck and Alex Iwobi, who returned to the bench to leave Aaron Ramsey in a more advanced midfield role.
West Brom manager Tony Pulis made three changes from the side that drew 0-0 with West Ham, reverting to a back five with Allan Nyom, Jake Livermore and Hal Robson-Kanu replacing Chris Brunt, James Morrison and Matty Phillips as the Welshman looked for his first win away at Arsenal.
