Brendan Rodgers has blasted Cardiff City owner Vincent Tan, accusing him of "knowing nothing about football".
The Liverpool manager was defending Cardiff boss Malky Mackay who was involved in a public disagreement over January transfers with the controversial businessman.
Tan has made a number of bizarre decisions since his takeover in 2010.
Last season, the Malaysian billionaire changed the club's colours from the traditional blue to red, a move which angered supporters.

Tan then sacked Cardiff's head of recruitment Iain Moody in October and replaced him with a 23-year-old intern from Kazakhstan who happened to be the son of a friend.
Rodgers brought up the case of Moody in his criticism of Tan:
"I worked with Iain Moody at Watford, one of the most authentic people you could ever meet. My only conclusion is you have a business guy operating the club who knows absolutely nothing about football. He has obviously been a successful businessman. Congratulations but football is like no other business!
"When I see what Malky has had to put up with, to see him being questioned I find it remarkable. Especially when supporters there look up to him and respect him for what he's done."
