Lacazette opens the scoring for Arsenal against the Baggies

Alexandre Lacazette scored twice as Arsenal beat West Bromwich Albion 2-0 in the Premier League at the Emirates Stadium tonight.

Lacazette scored a goal in each half to become the first Arsenal player in Premier League history to net in his opening three home appearances. Brian Marwood scored in his first three league appearances at home for Arsenal in September 1988 – prior to the Premier League era.

The victory ensured that Arsenal maintain their 100% win record at home this season in the Premier League, UEFA Europa League and EFL Cup.

The Gunners have now won their last eight Premier League games at the Emirates, their longest such run at home since April 2015 (nine successive wins).

Victory for the Gunners lifts them to seventh position in the Premier League table, one point behind fourth-placed Tottenham and six points behind leaders Manchester City.

Arsenal started brightly with Alexis Sanchez shooting just past the post from a free kick.

West Brom should have opened the scoring in the 7th minute.

Jay Rodriguez was brought down by Shkodran Mustafi in the penalty area, but referee Bobby Madley didn’t award a spot kick.

Rodriguez got back to his feet and his shot was turned onto the post by Petr Cech.

Jake Livermore fired the rebound wide of the post with the goal gaping.

Arsenal took full advantage of the let-off when Lacazette opened the scoring in the 20th minute. He headed into an open net after West Brom goalkeeper Ben Foster tipped Sanchez’s free-kick onto the crossbar.

The Baggies went close to equalising in the 38th minute, but were denied when Nacho Monreal acrobatically cleared a Rodriguez header off the line and over the crossbar.

Lacazette got his second goal from the penalty spot in the 67th minute.

Allan Nyom barged over Aaron Ramsey in the penalty area.

Lacazette stepped up and fired the ball past Foster into the bottom right corner of the net.

It was the Frenchman’s fourth goal since his club record £46.5m summer move from Lyon.

It was Arsenal’s 100th successful penalty in the Premier League – only Liverpool (112) and Chelsea (107) have scored more.

West Brom drop to 12th position in the Premier League table – on the night Gareth Barry broke the Premier League appearance record. It was his 633rd Premier League appearance.

This was the 10th time that Tony Pulis has managed a team at the Emirates Stadium in the Premier League – he’s lost every one with a combined score of 22-3.

Arsene Wenger has won all 11 of his home games against teams managed by Pulis, 10 in the Premier League and one FA Cup game at Highbury in 2005.

West Brom have lost more away Premier League games against Arsenal (10) than against any other side

Arsenal have scored in all 23 of their Premier League meetings with West Brom, the best such 100% record in the division.

Each of the Gunners’ past seven home wins have come on a different day of the week.

Next up for Arsenal is a trip to Belarus to take on BATE Borisov in the Europa League on Thursday and then a home match in the Premier League against Brighton & Hove Albion on Sunday.

Arsenal: Cech 6, Bellerin 7, Kolasinac 7, Mustafi 6, Koscielny 6, Monreal 7, Xhaka 6, Elneny 7, Ramsey 7 (Maitland-Niles), Sanchez 7 (Ozil), Lacazette 8 (Giroud)
