West Ham vs Arsenal: PGMO to 'be vigilant' over grappling at set pieces after 'clear and obvious' foul on David Raya

Chief refereeing officer Howard Webb says the PGMO will continue to "be vigilant" over "impactful" grappling at set pieces following the "clear and obvious" foul on Arsenal goalkeeper David Raya.

West Ham were denied a 95th-minute equaliser on Sunday when referee Chris Kavanagh ruled out Callum Wilson's strike after VAR official Darren England recommended an on-field review.
