Arsenal kept up its 100 percent home record this season with a 2-0 win over West Bromwich Albion in the Premier League on Monday, with new club-record signing Alexandre Lacazette grabbing both the goals.
West Brom had lost on its previous six visits to the Gunners but started the match brightly and was even denied a penalty after only seven minutes of play.
Gareth Barry, appearing in a record 633rd Premier League fixture and the Baggies' captain for the night, released the ball to Jay Rodriguez in the area, who cut back and was brought down by defender Shkodran Mustafi.
