Football managers who wear a suit on the sidelines during matches get a better performance from their players than coaches who wear sports gear, according to a study.
Sport psychologist Dr Richard Thelwell, of Portsmouth University, reckons players have more confidence in the strategy and tactics of a coach in jacket and trousers - although a track suit is essential on the training ground.
"I'd advise managers that on a match day, when strategy and motivating a performance is important, you may get a better response in a suit.
"Trackies for training, of couse, and for those sessions on reacting to fouls probably a tutu, or maybe leotard, leggings and legwarmers - real theatrical or dance movement class stuff.
"And show them a film of James Brown on stage - you know, when he collapses and has to be helped off in a blanket. Brilliant. Drogba could learn a thing or two."
