Arsenal v West Ham will bring back happy memories for Unai Emery, as it was the fixture that brought his first victory as our head coach - but it was not all plain sailing.
The Hammers took the lead, and even after we equalised they continued to threaten before an own goal and Danny Welbeck's late strike sealed a hard-fought 3-1 win.
The reverse fixture at the London Stadium should prove equally testing. Manuel Pellegrini, after a difficult start, has steered his side up to 10th in the table and with Felipe Anderson one of the stars of this Premier League season, plus former Gunner Samir Nasri added to their ranks, they have the firepower to cause us problems.
