Rafael Benitez has admitted he can be not very nice when he is angry, but insists he has moved on from his feud with Jose Mourinho.
The two men, who have both managed Chelsea, Inter Milan and Real Madrid, go head-to-head on Saturday, this time when Benitez takes his Newcastle team to Old Trafford to face Mourinho's high-flying Manchester United.
They have not met in the Premier League for more than 10 years but the rivalry which brewed between them during their spells in charge at Liverpool and Chelsea, respectively, sparked a war of words with the genial Spaniard twice dumping the Blues out of the Champions League.
