The Dutchman was sorely missed, as their neighbours ran riot at the Etihad, thrashing the champions 4-1, but David Moyes is hopeful the former Arsenal skipper will be available against the Reds or against West Brom this weekend.
“We thought Robin would be okay. We gave him every chance. It’s nothing serious,” Moyes told the the club’s official website.
“He could be involved on Wednesday or next weekend.
“I don’t think it’s that bad, we thought he was going to make it. He just felt something in his groin.
“He did a bit of training in the last couple of days.
“But he just felt it when he did any sharp movements and he didn’t want to aggravate it, so we took the decision [to not play him].”
