Barcelona will be hoping to return to La Liga's 1:1 rule before the end of the season, as this will allow them to spend money more freely during next summer's transfer window. However, even if this happens, they will need funds to be brought in so that they can do as much business as possible.
There have been several players who have been linked to leave Barcelona, such as Andreas Christensen and Eric Garcia. However, another avenue the club could exploit is sell-on clauses.
One of the most significant would be for Francisco Trincao, for which Barcelona has a sale of 50%. He has been linked with a number of Premier League clubs in recent months, but second SportSporting CP has no intention of selling the Portuguese winger.
It would be very disappointing for Barcelona if Trincao was not sold next summer, because this would mean that they are missing a very significant amount of money. However, they may still have some hope.
