When the Dutchman joined the Reds he said he chose the no.20 shirt because he was determined to help the club chase a 20th league title.
"I think I’ll keep it,” he said. “I have the option to take no.9 but I don’t think I’ll do that. I’ll stick with what is right and what feels good.
"Also, I don’t want to be harsh to the fans who have no.20 on their kit. I don’t want them to have to buy a new shirt. It's been a good number for me and now I can at least celebrate the 20th trophy for another year. I’ll stick with it.”
