Paul Merson described Arsenal's 3-1 victory over Bayern Munich as a "huge statement", saying the result will make everyone around Europe stand up and take notice of Mikel Arteta's side.
Second-half goals from Noni Madueke and Gabriel Martinelli fired the Gunners to all three points in their heavyweight Champions League clash with Bayern, stretching their perfect record in the competition to five victories from five matches to leave them top of the 36-team table.
It means Arsenal, who are now unbeaten in their last 16 games, are now top of the Premier League and Champions League tables.
"It's a huge statement from Arsenal," former Gunner Merson said.
"That goes all around Europe. People will be watching and seeing this result. They will be saying 'wow', especially because of what Bayern have done to Arsenal in recent years.
"This Bayern Munich team are blowing everyone away. I know the Bundesliga is not like the Premier League, but they are proven in Europe. They go deep in European competition.
"Arsenal were outstanding.
"The first half was touch and go. Both sides had their moments, but in the second half, Arsenal steamrolled them."
Merson went on to praise Arsenal's strength in depth after substitutes Madueke grabbed his first goal for the club and Martinelli scored on his return from injury.
Martin Odegaard also came on as he returned to boost Arteta's options.
However, despite the Gunners' strength in depth, Merson singled out Declan Rice, who was man of the match against Bayern, as Arsenal's most important player.
He said: "Noni Madueke, Gabriel Martinelli, Riccardo Calafiori, Martin Odegaard and Ben White came on. They were the five subs and they walk into the first XIs of most teams.
"For how big the squad is and how good it is, they cannot afford to lose Declan Rice. The man gets better and better and better.
"He was absolutely outstanding and he ran Bayern into the ground.
"He is Arsenal's most important player - one million per cent. But Martin Zubimendi deserves a mention too. He was phenomenal."

"Sit down and buckle in on Sunday", he said.
"This is a Super Sunday. Chelsea vs Arsenal is a massive football match.
"If Arsenal win it, I think it is good night nurse. I think it will be all over.
