#3 Best: Marco Arnautovic

Arsenal led their way in the game by dominating possession and trying to find gaps between West Ham's back line, but it was the Hammers who looked more perilous whilst getting forward.
Arnautovic was one player who was at the middle of almost every West Ham attack. He initiated counter-attacks, sparked pace and life into the game by taking on defenders, passed around safely and tucked away a fine goal to give his side the lead.
His link up with Anderson showed promising signs for Pellegrini, not only in this game but also in the outings to follow. His energy coupled with the work rate left the Gunners' defenders back-peddling.
He was unfortunately subbed off just before the hour mark and the East London side's attacking creativity saw deterioration.
