Bjorn Kuipers is the designated refeee for Barcelona's clash with Inter Milan in the Champions League. There's nothing at stake for Barca, who are through top of their group into the knock-out phases.
Kuipers refereed Liverpool v Barcelona last season, where the Catalans collapsed 4-0 at Anfield.
The Dutch referee is one of those chosen for important games in recent season. He was in charge of the 2014 UCL final where Madrid beat Atletico in Lisbon and did the Europa League final the previous year.
He first refereed Barcelona in a 2-0 win over Dinamo Kiev in 2009-10.
