Mikel Arteta's role in Arsenal's third goal against Watford has been questioned by former Premier League referee Dermot Gallagher.
Bukayo Saka scored one goal and set up another as Arsenal moved into the top four with a hard-fought 3-2 win at Watford after Martin Odegaard had given the visitors an early lead.
But Arteta's role in the win has come under scrutiny after Gallagher appeared to suggest the refereeing team made a mistake.
