Thanks to Martin Odegaard’s well-taken second-half penalty, the Gunners have won their last two Premier League games.

After Takehiro Tomiyasu was dismissed for collecting a second yellow card for a foul on Jordan Ayew, Arsenal played poorly and spent the final 30 minutes defending in their own end zone.

But Mikel Arteta’s team was steadfast in repelling their adversaries’ assaults, and they held on to earn all three points.
