Van Dijk was surprised that City were unable to score against Wolves on Sunday.
Reds centre-back Van Dijk said he thought it would be a "difficult game" for City but not as tough as it eventually proved.
“I didn't expect that, of course," he told Sky Sports.
“Everyone expected a difficult game for City, but City at home but it doesn't happen much that they don't even score one goal at home.
“A great performance from Wolves, you have to give credit to them but you know the situation, you can't really say much about it.
“They will try to bounce back from it and until then we've just got to focus on our international football of course."
