Ryan Giggs ended up winning the PFA Footballer of the Year award this season.
“Every time I watch Manchester United, being a Liverpool player, you want them to lose,” Gerrard told Sunday People.
“But Vidic has been a rock.
“He and Rio Ferdinand have been superb and they have saved United so many points this season and, for me, United owe those two big time.”
Gerrard believes Vidic’s poor display against Liverpool may have cost the Serbian defender the award.
“Maybe it’s been a bit harsh on Vidic,” he added.
“I still voted for him in the PFA awards and, if I’d had a Football Writers’ vote, I would have voted for him again, because he has had a magnificent season.
“Possibly, he’s been judged because of the incident against us at Old Trafford when he didn’t deal with the ball and Fernando [Torres] scored. Maybe that’s gone against him for both awards.
“He’s still had a great season and it’s just unfortunate – but maybe I have to thank Fernando for this award!”
