Former Bayern Munich midfielder Danijel Pranjic has expressed his belief that Louis van Gaal is the greatest footballing mind he has ever met, but that the Dutchman's abrasive personality means players can only put up with him for so long.
Pranjic, something of a cult hero in Bavaria due to his ability to play in several different positions, spent two years working under the veteran coach at the Allianz Arena, winning the Bundesliga, the DFB-Pokal and reaching the final of the Champions League.
Despite Van Gaal's obvious nous given the titles he won during his time with Bayern, Pranjic noted that while he had a good relationship with the 68-year-old, others found him difficult to work under due to his constant pursuit of perfection.
