Chelsea fullback Van Aanholt winning praise at Vitesse
De Visser says Vitesse coach Fred Rutten has rescued the young fullback's career.
"The best example is perhaps Patrick van Aanholt. Last season he had a dramatic year. John van den Brom didn't treat him well and failed to work with him. That was a big mistake.
"But then Rutten went to work with him and now he's come on in leaps and bounds. Therefore I am, but also Chelsea, so happy with Rutten as a trainer."
