The pair have struck 39 goals between them this season and will resume their partnership at Wembley on Saturday against Northampton in the League Two play-off final.
Bermuda international Wells, 22, has fired 25 of those goals and Hanson is convinced he has a big future.
"He's very good," Hanson said. "He's a young player, very hungry. He's quick and he anticipates things very well.
"He brings the best out of me as well. When I'm winning the headers, he's getting on them, which makes me look a better player.
"We've got a good partnership. We're both scoring goals and hopefully we can get a couple on Saturday.
"It's all about whether he can keep his feet on the ground, he's got unbelievable ability.
"The longer the season's gone on teams have tried to suss him out, so he might have to mix his game up a bit more, but I'm sure he can play at a higher level in the future.
"A lot of people say our partnership is the little and large combination. As a partnership I think it's the best one I've played in.
"He's the fastest guy I've played with and his anticiapation is very good. He always seems to be near and around me, collecting the knockdowns. He's a good player."
