Ferguson was reportedly upset by an article Cass wrote on the Welsey Sneijder situation, in which he claimed the United manager had given up on signing the Dutchman and was annoyed at his wage demands.
The two men came face to face as United left the stadium following their friendly win over Barcelona in the U.S., and Ferguson didn't hold back. "You and your paper can f**k off," he said, before storming off.
It's not the first time Ferguson has clashed with the British press, and it won't be the last.
