The striker has been partnered with Antoine Griezmann for France and Nicholas thinks Wenger should take note.
The striker is currently at Euro 2016 with hosts France, where he has been a regular in Didier Deschamps’ team.
He had headed into the tournament surrounded by mounting criticism as the national fans turned against him.
He has turned public opinion of him in his favour during the tournament though with a series of impressive performances.
Much of Giroud's success has been built on the relationship he has built with Atletico Madrid star Antoine Griezmann, and Nicholas believes that partnership should be an eye opener for Arsenal boss Arsene Wenger.
“The French don't like him [Giroud} because he can be too static and cumbersome but if you put somebody up around him he's a lot more effective,” he told Sky Sports.
“I'm his biggest critic and fan at times and it's an eye opener for Arsene Wenger about what playing somebody alongside him does.”
It now remains to be seen whether Wenger will take inspiration from France this summer and find a partner for Giroud.
The Arsenal striker has certainly been impressive for his country this summer, looking a far cry from the player who struggled in the second half of last season.
Much of his success has come from the partnership with Griezmann, and should Arsenal secure a striker this summer it is certainly an approach that Wenger should consider taking.
