Top of the table Arsenal claimed a hard fought 2-0 win over managerless Crystal Palace at Selhurst Park, as Mikel Arteta slotted home a penalty before being sent-off.
Olivier Giroud made sure of the points as he headed home Aaron Ramsey’s cross with just a couple of minutes left.
Crystal Palace caretaker coach Keith Millen had set up his side to stifle Arsenal, and it worked as they saw out the opening 45-minutes.
However, just minutes after the re-start, Arsenal claimed the lead as Adlene Guedioura recklessly slid in on Serge Gnabry and Arteta slotted home the resulting penalty.
Arteta was at the centre of the action as he then saw red for hauling down Marouane Chamakh when he was the last man – although he still had some way to go before getting in on goal.
Palace looked to take advantage of the extra man, and they tested Wojciech Szczesny on a couple of occasions before the game was settled by Olivier Giroud.
