Ronald Koeman has chided Gerard Pique for his comments over alleged pro-Real Madrid biases among the country's match officials after it was confirmed that the defender was under investigation.
The veteran centre-back's claims are to be examined by the Royal Spanish Football Federation to ascertain whether he broke the organisation's rules on honouring impartial respect for referees.
If found guilty, the Blaugrana veteran could face a significant ban, handing a further blow to Koeman's team as they continue to face struggles in both domestic and European competition.
