Tottenham beat Arsenal 1-0 at Wembley last Saturday to extend the gap between the two teams in the Premier League table to seven points.
Arsenal fans went into the game confident with new signings Pierre-Emerick Aubameyang and Henrikh Mkhitaryan starting alongside Mesut Ozil, who recently signed a new deal.
But Merson says the trio did not turn up and Hector Bellerin, who has received some criticism from supporters of late, was one of the only players to come out of the game with credit.
“I’m a big fan of this lad,” Merson said of Mkhitaryan on Sky Sports.
“But if you watched the front three last week of Ozil, Mkhitaryan and Aubameyang, they show nowhere near the same urgency as what you get with the front three of Tottenham. Not anything like it.
“Everything that Tottenham front three do is meant, is zipped, is bang, is movement.
“A ball comes to Mkhitaryan on the left, you’re playing at Wembley which is a snooker table, and he it it 70 yards over everybody’s head and he just walked back.
“There’s no zip, even when Aubameyang’s offside it’s a smile to Jack (Wilshere), not like ‘that’s not offside’ or have an argument, just to put it in the ref’s head next time or the linesman’s head.
“The goal comes from before long Mesut Ozil was going to fall asleep, or Mkhitaryan, and the full-backs were going to a load of time on the ball to cross the ball in, and that’s what happened.
“Watching the game, for me Bellerin played well.
“I thought Bellerin played well, I didn’t think (Heung Min) Son had a touch, I thought he defended well.”
