Until now, Sanllehi had been the director of football and in charge of negotiations when it came to signing new players.
Club president Josep Maria Bartomeu will present a new sporting structure in the next general assembly, which will see the role of negotiator with other clubs and the likes of UEFA and FIFA be absolved into another position.
In the new set-up, Pep Segura will continue as general manager, Robert Fernandez will stay on as technical secretary and both Jordi Mestre and Albert Soler are expected to remain as vice-president and sporting director, respectively.
After 15 years of service in various roles, Sanllehi has decided to leave the club of his own volition having seen that he would not fit into the new system.
The Catalan wanted to make sure that his departure was on friendly terms before the January transfer window.
Sanllehi was understood to be upset and frustrated this summer, particularly the departure of Neymar. It was Sanllehi who had saw through the tough negotiations with Santos to sign the winger in 2013 and he had enjoyed a good relationship with the Brazilian until the second offer from Paris Saint-Germain.
It was in fact Sanllehi who convinced Neymar to turn down the offer from Paris the first time, in 2016, but he could not convince the forward to stay this summer.
He held various talks with both the player and his father during the club’s tour of the United States, but was unable to change Neymar’s mind.
The loyal club servant was also left humiliated by the decision of the club’s coaches to pull out of a deal for Jean-Michael Seri when he was already in Nice to negotiate a deal.
Multilingual and low-profile, he began life at the club as manager of FCBMerchandising in 2002 just a year before the arrival of Joan Laporta as president. His work there impressed club bosses and caught the eye.
In 2008, he moved on to become director of football, a role that he continued to hold after the election of Sandro Rosell.
With such rich pedigree, it seems unlikely that Sanllehi will have to wait long for offers of employment from other clubs.
