Former England international Danny Mills has thrown his support behind the Brazilian Soccer Schools (BSS) methods after seeing first-hand the benefits the training has brought to his own children's game.
Mills played for Leeds United between 1999-2004, helping the club to reach the semi-final of the Champions League, and in the same period he became a prominent member of the England set-up, playing every game of the Three Lions' 2002 World Cup campaign.
The former right-back then helped Middlesbrough to lift the League Cup trophy in 2004, the club's first-ever major trophy, whilst his career also included spells with Manchester City and Charlton Athletic among others.
His opinion, therefore, comes from experience, and he admits he was pessimistic when he first took his sons to the Brazilian Soccer School centre.
"At first I was a little sceptical until I took my son along to a session," Mills admitted.
However, with both his sons now attending several sessions a week, Mills is full of praise for the training that has already helped players such as Theo Walcott, Micah Richards and Michael Owen improve their game.
"I was so impressed that my eldest son now trains four times a week - two technical and two conditioning sessions - and the youngest twice a week," Mills added.
