The England international has broken back into the first team at The Emirates this season after having struggled for both form and fitness with the Gunners in recent seasons.
Wilshere has helped Arsenal to reach the Europa League quarter-finals against CSKA Moscow as the Gunners look to try and qualify for next season’s Champions League by winning the competition.
The midfielder is out of contract at the end of the season, meaning that Arsenal could risk losing him on a free transfer in the summer unless they tie him down to a new deal.
And former Aston Villa midfielder Reo-Coker feels that it would be wise for Wilshere to leave Arsenal this summer and benefit from a new challenge somewhere else.
Rio-Coker told Sky Sports: “I think it would be good for him to get a change of environment.
“It looks like it is time for him to try something new, a new chapter, move away from Arsenal.
“If I was Jack I would see that the writing is on the wall.”
The 26-year-old has scored two goals and made three assists in all competitions for Arsenal so far this season.
He has managed to notch up 35 appearances in all competitions as he has managed to stay largely injury free this campaign.
Arsenal will return to Premier League action after the international break when they take on Stoke City at The Emirates on 1 April.
