Martin Braithwaite was booed by Barcelona supporters ahead of Sunday's friendly against Mexican side Pumas UNAM.
Barcelona are trying to release Braithwaite, 31, to free up space in their transfer budget. As per La Liga rules, the Spanish giants need to make sales before August 13 if they want to register their new signings - including Robert Lewandowski and Jules Kounde.
Braithwaite still has two years left on his existing deal and is refusing to leave Barcelona this summer unless he's fully compensated. The Denmark international is unlikely to get the same salary at another club and is well within his rights to be paid in full.
