After the mutual separation, former pro rider Marc Sergeant takes over the position. He operated in directeur sportif and management roles at the outfit before the break-up of Omega Pharma and Lotto.
"It is an internal reason – we had a very small structure next to the sporting structure, and now we will try to build up a larger structure with Marc," team spokesman Arne Houtekier told VeloNation.
"There was a lot of things to do after the split from Omega Pharma and Bill did a lot of work in that area. It would not be true to say that he had not done well – that was not the case. Bill had a lot of things to do, although it was sometimes difficult handle the financial, commercial and organisational things.
"That was too much for one person and now the board has decided to split it up and have a few people working in those areas.”
Sergeant, 53, won stage five of the 1987 Tour de France and was Belgian road race champion the year before.
