Red Star Belgrade players have been told by manager Slavisa Stojanovic that they need to stop eating meat pies and drinking beer.
The warning is believed to have come after the club struggled against Icelandic outfit IBV in their second round qualifier in the Europa League.
"All the hard work you have done in the searing heat of pre-season build-ups will amount to nothing if you keep eating meat pies before practice and drinking two or three beers after it," Belgrade media quotes Stojanovic as saying, according to the Daily Mail.
Despite a poor performance against IBV, Red Star secured a 2-0 aggregate victory.
