After returning to Arsenal at the end of last season from a loan spell with the Cherries, Wilshere is hoping to play as regularly as possible in order to try and win a place in the England side for the 2018 World Cup.
Recent reports have suggested that he would even leave Arsenal during the January transfer window in order to do so with West Ham said to be interested in signing him.
Arter said of his former team-mate, "When I look at England's midfielders at the minute they are all good, but Jack brings something different the midfielders they have.
"If it wasn't for his injuries, there is no doubt in my mind he would be an England regular. Once he gets a run of games, people will see how much of a good player he is."
