Born in Canada, Caolan spent two years at Ipswich Town as a scholar while Marcus Stewart scored forty goals for the Tractor Boys - during a two-and-a-half-year spell at Portman Road.
Walsall's new number nine is keen to learn from Stewart as he looks to get among the goals and help the Saddlers bounce back from last season's relegation.
Speaking via the club's official website, Caolan said; "I haven’t told him this yet but I was at Ipswich as a scholar and his name is always mentioned around those parts. I’m look forward to working with him and picking his brains and seeing how much I can get out of him."
Despite having something of a stop-start career, Lavery has plenty of experience and has won three promotions in the last three years with Sheffield United, Rotherham United and Bury respectively.
Caolan scored six goals in all competitions last season while on loan with the Shakers and has given Saddlers fans a bit of insight into what they can expect to see from him over the 2019/20 campaign.
He continued; "I am a very honest player and I leave everything out there on the pitch. I am a hardworking player and I like to put defenders under pressure. I am a striker that likes to get in behind the backline."
The 26-year-old former Northern Ireland under-21 international will be competing with Elijah Adebayo, Josh Gordon, and Mitchel Candlin for a place up front this season, but insists he’s not afraid of competition and sees it as a positive.
Caolan added; "Every club that I have been with, competition is always good. You’re always working on each other to better each other and you’re always looking to keep everyone on their toes. At every club, no matter where you are up and down the country, you need to have a good strike force."
