Chelsea masseur Billy McCulloch wore the initials of former manager Roberto Di Matteo on his club jacket over the weekend.
The Blues staff member was spotted on camera during Chelsea's 2-1 victory over Arsenal on Sunday stood behind interim boss Rafael Benitez.
The masseuse usually dons a jacket with his initials 'BM' on the front but at the weekend they were replaced with the name of the coach who was sacked by the Blues in November following a disappointing Champions League campaign.
Meanwhile, Benitez, who has signed a contract until the end of the season, has admitted that he would like the role permanently.
