Mikel Arteta warned Arsenals title rivals that their ruthless 4-1 rout of Aston Villa showed they are on track to win the Premier League for the first time in 22 years.

Martin Zubimendi doubled the lead moments later before Leandro Trossard and Gabriel Jesus produced clinical finishes to complete the demolition.
