In the course of his time at the club, Manchester United, Dimiter Berbatov disclosed that Anderson was his worst trainer.
The Bulgarian also rated ex-captain, Gary Neville as the best trainer.
According to Berbatov, Anderson regularly “pissed” him off during their training session.
Berbatov shared a dressing room with Neville and Anderson during a successful four-year stint at Old Trafford, during which the Red Devils won two Premier League titles, the Champions League, two League Cups, and the Club World Cup between 2008 and 2012.
“The worst trainer… I must say Anderson. Although he had a lot of quality and talent and was really good on his day, at training sessions, he really pissed me off sometimes.
“Like I maybe used to piss some players off, Anderson used to piss me off, Berbatov” said while speaking on behalf of BetFred.
Anderson made 181 appearances for United, between 2007 and 2015.
