Steven Caldwell

For the modern footballer, there is no one “clear cut path” to professionalism. Blue Devils FC President Steven Caldwell can attest to that. The Stirling, Scotland born defender rose up through the ranks at Newcastle United, and got his professional debut under Bobby Robson, playing alongside legends like Alan Shearer, Shay Given, and Gary Speed.

In his time at St. James’ Park he was part of a club playing Champions League matches against the likes of Inter Milan and Barcelona. But it wasn’t all matches at the San Siro and Camp Nou. He had several loan spells to lower league sides before becoming an automatic on the team sheet. Even then, that didn’t come until he moved on to Newcastle’s arch-rivals Sunderland. Caldwell’s career trajectory was never straight to the top, and they rarely ever are. Steven can speak to the agony of relegation, and the absolute thrill of captaining his Burnley side to Premier League promotion in front of 90,000 fans at Wembley. Along the way, Caldwell managed to find time for 12 Scotland International Caps in two World Cup Qualification rounds before ending his career captaining Toronto FC.

Now that he has hung up his boots, and he’s allowed to plot out his own future, he wants to use his experience to help a next-generation cut their own path. He has been named to the Canadian Men’s National Team as an Assistant Coach and joined Blue Devils FC in the early stages to help build the organization. There was no secret to his success. Determination and work ethic is what got him as far as he did.

“We want to improve the entire program not just tactically and technically, but psychologically as well - teaching these young players across Ontario what it really means to be a professional football player. How much intensity it takes in training, and how much focus and dedication is needed.”

Part of Steven’s decision to come on board with Blue Devils FC was because of the ambitious group that he will be working with. “I am joining an already successful team of qualified and experienced individuals in Duncan, Billy and Shen and I will look to lend my support in all areas of the soccer club.”

Blue Devils FC Head Coach Duncan Wilde is a product of first the City and then United Academies in his native Manchester. His counterpart on the touchline is another Scotsman – Billy Steele, who plied his trade with Norwich City in the ’70s. Caldwell believes it is the sum of that whole which will work together in the clubs efforts to provide young athletes in Southern Ontario with the greatest possible opportunities.

“Through our vast list of contacts both in North America and Europe and some unique ideas in grassroots soccer, we hope to take an already outstanding program even higher and become a leader in soccer throughout Canada.”

While Steven’s connections from his playing days will be an asset to the team, possibly his greatest contributions will happen in the boardroom. Upon his retirement from playing the game, Steven moved into the role of Director of Corporate Development with Maple Leaf Sports and Entertainment. “My experience at Maple Leaf Sports and Entertainment allowed me into all sides of the game, not just the playing side and the technical side of it. Obviously, a lot of my work was with partnerships, ticket sales, community, everything that goes into Toronto FC, and the successes that they’ve had.”

All of these experiences will prove valuable as Blue Devils FC continues to build the organization in Ontario and beyond. “I’m very excited about what’s to come. We have a long road ahead of us, and a lot of difficult jobs, but we feel we are creating something very, very unique in Canada.”

Mauricio Flores

Soccer is the most played sport in the world with over 4 billion followers, and Mauricio Flores had the great fortune of being born, raised, and educated in a country where soccer is deeply ingrained in the culture. Originally from Mexico, Mauricio has accomplished much in the sport he loves, including playing professionally for 11 years. That experience has given him first-hand insight into, as well as a profound respect for, the beautiful game.

After his professional career came to an end, coaching came naturally for Mauricio. He now holds a USSF National A licence and has spent the last 16 years of his life learning, breathing, and living soccer in some of the most renowned soccer clubs across the globe. This has given him a unique perspective, and has been a driving force in his continual development as a mentor and a coach.

As Mauricio says, “Soccer is my life and passion! My goal is to pass along all my years of acquired knowledge to help guide young players who have aspirations to pursue a future career in soccer, as well as to provide a safe place for players to nurture their love of the game. I hope with all my heart that we can create a great soccer culture for all the new generations to come - uniting people through the beautiful game of soccer.”
