Liverpool midfielder Gini Wijnaldum was in Holland on Thursday for Wim van Hanegem's 75th birthday party.
Wijnaldum credits the former Holland star for helping him through a tough period in his career back in 2012 when he was with PSV.
"At the time I got a lot of criticism," Wijnaldum recalled to AD. "But Willem wrote a column about me that touched me.
"Willem stood up me in a very important period in my career and gave constructive criticism, which I could do something with.
"Then it went better. We have kept in contact since then."
