The 27-year-old says he has ambitions of playing in the Premier League before the end of his career and has called the Anfield side 'very special'.
"I still get goosebumps from 'You'll Never Walk Alone'.
"There are other great English clubs too, and I always liked Milan because so many Dutch played there.
"I am ambitious and want to get ahead - maybe at some point play at another club, whether in Germany or in England.
"But at the moment it is still far away. I feel good and try to achieve the maximum here."
