Neither Juan Mata or Fernando Torres heard alleged abusive remarks from referee Mark Clattenburg in Chelsea's heated defeat to Manchester United on Sunday, according to Blues midfielder Oriol Romeu.
Clattenburg is accused of making racially-aggravating remarks towards some Chelsea players during the match at Stamford Bridge, with the Daily Mail claiming the official used the phrase 'Spanish twat'.
There is no clear indication as to who the alleged comment was made about, but Chelsea used three Spanish players against Manchester United - Mata, Torres and second-half substitute Cesar Azpilicueta.
Romeu, another Spanish player available to Roberto di Matteo, was not required against Manchester United but says he has spoken to his colleagues about the incident.
The 21-year-old, though, has confirmed that neither he, Mata or Torres were aware of Clattenburg's supposed remark - but were informed about it by other Chelsea players.
"Neither Juan nor Fernando told me they heard it because from what I have understood they didn't hear anything," Romeu told Cope - a Spanish radio station.
"It was someone else who heard it, but not directly at them. It was another player who heard it and that is what they told me.
"I didn't hear anything as I left quickly to go home but after talking to Juan he told me there was some problem and he had to stay.
"I only know Chelsea made a complaint and I think there could really be a problem if what Chelsea players say happened really happened."
The Football Association have taken the decision to stand down Clattenburg from duty next weekend as they investigate the complaint from Chelsea about his behaviour.
