There was no favouritism involved in Benayoun being picked over Marin. It's well documented he and Benitez never got on. He was simply a better option than Marin and was trusted not to let the team down when given minutes. It tells you everything you need to know about Marin, that a 33 year old physically knackered player like Benayoun, who the club tried to get rid of that season only to be sent back by West Ham no less, was preferred over him. To think some people want to waste another year on Marin is mind-boggling.
