Pierre-Emerick Aubameyang was on the receiving end of boos and whistles from Real Madrid supporters when he was substituted after dazzling on his El Clasico debut for Barcelona on Sunday.
The 32-year-old scored twice at the Bernabeu, and provided an assist for Ferran Torres as Barcelona hammered their bitter rivals 4-0.
This took his tally to seven league goals in seven games since joining the Catalan giants from Arsenal at the end of January.
He may have fancied his chances of a hat-trick, but Xavi opted to take him off in the 71st minute with the result already wrapped up.
