The duo argued Arsenal would not have had the chance to win the match if Kavanagh had not increased the time allotted for the injury time.
The Gunners appeared set to drop at least two points after Bournemouth stunned them at the Emirates Stadium by taking a 2-0 lead.
The commentators wondered why the referee allowed Arsenal to play till the 97th minute after only six minutes were added on for injury time.
Keys asked, “I would ask about the time of the goal as 97 minutes had been played. I think Bournemouth will have reason to think, ‘where did you find that time?’ The referee will have a reason.”
Andy Gray added, “There were six minutes added on, you can see that in the top corner, and we were just approaching the 98th minute when Reiss Nelson scored.”
