Lee Dixon gave a blunt response to Nicolas Pepe's message to Mikel Arteta as the game progressed.
The Arsenal striker was signed for a club record of £ 72million this summer and is expected to have a huge impact.
But this campaign he has only started one Premier League game and has been used extensively from the bench.
New arrival Willian was the main man on the wing of Arteta, in partnership with Pierre-Emerick Aubameyang and Alexandre Lacazette.
This left Pepe on the sidelines and during the international break he expressed his frustrations.
“My goal is to play more. To have a little more playing time, ”the 25-year-old told French channel Canal Plus.
But Arsenal legend Dixon silenced the Ivorian in just three words.
On Twitter, he responded to the comments by saying, "Play better then."
