On the 1st of September in 2013, Spurs lost 1-0 to their bitter North London rivals Arsenal. Steffen Freund had returned to White Hart Lane as a coach at chairman Daniel Levy's insistence and had always sat next to Andre Villas-Boas on the bench. However, after the derby defeat, he and Villas-Boas had a huge disagreement over the teams approach and the substitutions that had been made in the match and, subsequently, Villas-Boas promoted Luis Martins and relegated Freund in the seating positions. Martins, who arrived at Tottenham with Villas-Boas as part of his coaching team when he was appointed as Spurs boss in 2012, became the managers primary confidant and assistant, which inevitably caused tensions at the training ground and Freund felt alienated as his role vanished. This would be one of a number of disagreements which aided Villas-Boas' downfall.
