Coerver Coaching
In 2022 he kickstarted 2022 with a new soccer school set to run throughout the whole year named based in Torquay.
The Coerver Method- named after Dutchman football manager Wiel Coerver – is a football coaching technique which Coerver created. By analysing videotapes of various great players including Pelé, he devised a new concept in football which advocates that skill could not only be inherent with the young players but could also be passed on in a comprehensive academic way. Under this technique, players progress in a structured manner, pyramidal, from basics of ball mastery to a tactically driven group attack. They would be exposed to the other essentials like Receiving and Passing, Moves, Speed and Lethal Finishing.
