Coloccini admits the Dutch destroyer is one of the divisionâ€™s form players.
â€śI think we have a test every week, but Robin right now is on fire, he is unbelievable and weâ€™re going to have a tough job. We will have to do well to stop him scoring,â€ť he told the Sunday Sun.
â€śI donâ€™t know whether he is the best as there are a lot of good players. I donâ€™t know if he is the best, but of course, he is one of the best and we have to be careful.â€ť
