London Winning a Premier League title is never going to be a stroll in the park and Arsenal got a painful reminder of that on Sunday, with a 3-2 home defeat by Manchester United increasing the jitters for the north London club.
At times this season, Mikel Artetas side have looked like they were disappearing into the distance at the top of the table, with reigning champions Liverpool struggling and Manchester City still not the relentless force they once were.
With City and Aston Villa dropping points in recent weeks, Arsenal could have built a daunting advantage as they seek to win their first title for 22 years after a series of near misses.
