Shortly after the game, a 2011 Telegraph interview with Andre Villas-Boas resurfaced, during which he admitted that while working under Chelsea manager Jose Mourinho he would "travel to training grounds, often incognito" to secretly watch opposition in training to illicit further information. "There were talks about Chelsea used to do this years ago - I certainly wasn't aware of it and I don't believe it at all. Although the Leeds employee was removed by police at the request of Derby, he was not breaking any laws by observing the training session. Derby return to action on Wednesday evening as they travel to Southampton for their FA Cup third-round replay.
