Wilshere joined the south coast club in search of regular football on the last day of the transfer window and made his first appearance by playing 45 minutes of Saturday's 2-1 friendly defeat to AC Milan at the Vitality Stadium.
Regarding the talented midfielder, Howe said: "We saw the potential of the team with him in it and there will hopefully be some exciting times ahead and he can provide that link between our midfield and attack which we desperately need.
"He has a creative eye, which anyone who has seen Arsenal down the years will know how good he is with his decision making in those areas.
"I don't think there is any doubting his quality. If we can get enough ball in dangerous positions he will certainly hurt teams."
