We’re delighted to announce a new partnership with internationally respected tennis coach and educator Professor Alberto Castellani, further strengthening our commitment to supporting the coaches who help players progress at every level of the game.

Alberto is one of the most experienced figures in international tennis coaching, with a career spanning hundreds of ATP Tour events, Challengers and Grand Slams and experience working with players including Janko Tipsarevic, Ivo Karlovic, Marc Rosset and Rainer Schuettler.

He is also President of the Global Professional Tennis Coach Association (GPTCA), reflecting a career dedicated not only to developing players but also to educating coaches and raising coaching standards around the world.

It’s that passion for coaching and player development that makes Alberto such a natural fit for Mantis.

Fabrizio Caldarone, our European Marketing Director, said:

"Alberto has an incredible depth of experience at the highest levels of tennis, but what really connects him with Mantis is his passion for coaching and helping people improve.

"Coaches have always been hugely important to us. They introduce people to tennis, help players progress and keep them engaged with the sport. They also spend thousands of hours on court working with different players and equipment, which makes their knowledge and feedback incredibly valuable."

Through our partnership, we’ll work closely with Alberto, drawing on his extensive experience and international coaching knowledge while supporting his work within the game.

It’s also another important step in building closer relationships with coaches at every level — from those developing the next generation of professional players to the thousands helping recreational and club players get more from their tennis every week.

As Fabrizio explains: "We don't want our relationship with coaches to simply be about supplying rackets and balls. We want to listen to them, learn from their experience and involve them in the development of Mantis. Alberto shares that philosophy, which makes this partnership particularly exciting for us."

Ultimately, this partnership is about something we both believe in: helping people get better at the game they love.

Play is Progress.
