Graeme Souness hit out at Pierre-Emerick Aubameyang after he appeared to take another dig at Unai Emery after Arsenal's 4-0 win over Newcastle.
The Gunners claimed their first win since New Year's Day as Aubameyang struck the opener in a rampant second half display at the Emirates.
After the game, Aubameyang claimed Arsenal"feel better" now they are playing under Arteta.
"We have an idea of playing," he said. "It's very clear and we are trying to maintain this level."
He was stood alongside teenage prospect Bukayo Saka, who has flourished under Arteta, as he became the latest Arsenal star to suggest they had no clear plan before Emery's sacking.
Speaking on Sky Sports, Souness said: "I don't like that. I don't like players talking like that. You know what you have to do.
"OK, there's one young player and one senior player there, Aubameyang is 31.
"When you get to a certain age, you know what you have to do to be successful at this level. You have to run around with enthusiasm, you have to be aggressive, you don't give the ball away cheaply, you attack things in an aggressive manner.
"I'm not talking about going out and fouling, just everything in the first half from Arsenal was passive and in the second half they played more aggressive. They played with more passion.
"To succeed at this level you must have all those ingredients, then when you lose the ball you sprint back into your position, get goal side as quickly as you can. The basic things.
"I get fed up with tactics, tactics, tactics. The first thing you have to get right, you have to have the ball. So to get to the ball, you have to get to the ball first.
"Once you're in possession, then a bit of team shape, bit of team play comes into action.
"To hear people say 'we now know what we're doing', I'm not accepting that.
"For a 31-year-old to say, 'it's now clear, we now know what we're doing', I'm not accepting that.
"He knows what he has to do to be successful. He'd have known that seven or eight years ago."
