Arsenal provided another reminder of their title credentials with a hard-fought 1-0 victory over Crystal Palace at Selhurst Park.
Martin Odegaard's second half penalty was the difference between the sides after Sam Johnstone fouled Eddie Nketiah following a well-taken free-kick by Gabriel Martinelli.
Roy Hodgson's side didn't give up and kept the pressure on the Gunners' goal - particularly after Takehiro Tomiyasu received a controversial second yellow card for a shirt pull on Jordan Ayew.
However, Mikel Arteta's side were resilient and made it two wins from two in the
Premier League this season.
