A Uefa report has backed Chelsea’s claims Barcelona coach Frank Rijkaard spoke to referee Anders Frisk at half-time of the Champions League tie.
Uefa’s venue director Pascal Fratellia said: “The referee told us he had contact with Rijkaard from the pitch to the front of his dressing room door.
“Rijkaard wished to say hello at the beginning of the tunnel and then tried to talk to him climbing the stairs.
“Frisk told him it was not the place or moment to speak about the match.”
Chelsea manager Jose Mourinho received a two-match touchline ban for suggesting Rijkaard was seen in Frisk’s dressing room.
Chelsea, who were fined £33,000 and labelled “liars” for the remarks, later accepted Frisk spoke to Rijkaard outside his room.
Neither Chelsea nor Uefa would comment on Fratellia’s report.
But it is unlikely Uefa’s ruling at last week’s disciplinary hearing will be affected.
