At least Mikel Arteta can always rely on Kai Havertz these days. The Arsenal striker scored for the seventh successive home game to match Robin van Persie’s record and inspire a dramatic comeback after his side found themselves behind against struggling Southampton.

Still without a win seven matches into the new campaign after being promoted last season, Russell Martin must have been dreaming of causing a major upset when the substitute Cameron Archer silenced the home crowd early in the second half. Havertz had other ideas and his equaliser three minutes later provided the impetus for Gabriel Martinelli to score a second before the outstanding Bukayo Saka wrapped up the points on a day that was almost one to remember for Aaron Ramsdale against his former club.
