Reid believes the Holland international will benefit from going back to basics.
"He's been caught out at key moments," says Reid. "At the moment he's in a rut where his mistakes are being punished with goals against him and he is the only one who can lift himself out of it.
"I always feel when you are making mistakes you should focus on getting the basics right again.
"Don't dwell on the ball if you have time and space. And don't try and defend too high up the pitch. At the end of the day we've all been through it."
