The Dutchman needed only one half-chance to haul United level with a crisply-taken finish, and Giggs conceded that the United new boy is brimming with confidence after a scintillating run of form.
"The keeper came rushing out but he's still a great finisher," said the Reds veteran. "I think everybody knew when he went through that there was only going to be one outcome.
"His confidence is just sky high at the moment. I read last week that a lot of the players think he's similar to Ruud in the respect that Ruud used to get a chance and more often than not he'd put them away. That's the case with Robin at the minute; his confidence is high, we're creating chances for him and he's putting them away."
