Marseille’s head of security Guy Cazadamont claimed he was thrown out of Stamford Bridge on Tuesday.
“I have never experienced such a reception in a European competition,” Cazadamont told Marseille’s website (www.om.net).
Chelsea later issued a statement on their own website (www.chelseafc.com) saying: “There were a number of incidents at Tuesday evening’s game involving the away support, all of which are being fully investigated by Chelsea Football Club.”
Cheslea will not comment further until their investigations are complete and “the results have been shared with UEFA.”
Cazadamont said on the Marseille website: “I was grabbed round the waist and was eventually thrown out of the stadium.
“I was expecting something else since everything always went pretty well when we played in Liverpool, Bolton, Manchester or Newcastle.”
Cazadamont claimed the 22 Marseille stewards, who travelled from France, were not allowed to supervise their fans in the stands and banners were confiscated at the stadium entrance.
“I went to the stands and the discussion was heated. But instead of dealing with my Chelsea counterpart, I had to talk to the stewards,” said Cazadamont.
