However, Merson has argued that for the first time this season, the 29-year-old failed to produce the same kind of high-octane performance that has terrorised defenders during this campaign.
Merson told Gillette Soccer Saturday, broadcast on 20 February at 12pm: "For the first time this season, Vardy looked very, very tired. It's the first time that I have watched him chase things and think 'I'm not getting this. I'm not going to get this ball'.
"That's not him. He chases anything to try to get a throw or get a corner and it buys his defence a lot of time. They can move up to the halfway line and get a breather.
"I didn't find that they got that breather in the second half, although the balls weren't that great coming out."
While Vardy was ineffective for much of the second 45 minutes in North London, his laboured display could be put down to his team playing with 10 men after the dismissal of Danny Simpson for two bookable offences.
Leicester are currently enjoying a weekend off after their early elimination from the FA Cup, but given their exertions in North London, 13 days without a game could not have come at a better time.
