The pair were team-mates at youth level for a number of years as they rose through the Gunners ranks and were both part of the 2009 FA Youth Cup-winning side.
Frimpong has gone on to feature regularly in Arsène Wenger's first team this season and Coquelin says his fellow midfielder has encouraged him to push on and work hard for his place in the squad.
"I am really pleased for him," Coquelin told Arsenal.com. "He had a big injury last season, and now he's back in the first team.
"It shows me that I can do it because the manager has confidence in younger players. I will just keep working hard in training and show the manager I can play in this team."
Coquelin has featured in Arsenal’s last two first-team outings, starting against Manchester United before coming on as a substitute in the weekend victory over Swansea.
The young Frenchman is determined to remain in Wenger’s line of sight following his loan spell at Lorient last season and wants to let his time on the pitch do the talking.
“If he uses me that means he has got confidence in me,” said Coquelin. “I have to keep showing I have the quality to play in the first team, and I can show that in training and in the games.
“Obviously I played a lot [at Lorient] so it gave me a lot of experience. I will try and bring that to Arsenal and keep improving.”Copyright 2016 The Arsenal Football Club plc.
