Centre backs pace issue

One of the problems that affects the gameplay is the pace of defenders. Why is it always so low?? The fastest CB (Micky van de Ven, known for his blistering speed) has only 126 as his base pace, whereas strikers like van Persie and even Ibrahimovic have way more. If you ask any football fan they'll tell you that van de Ven can easily bolt past them.

My example covered only the fastest CB, other CBs have way less pace and there's no reason to make them that slow.
