A young promising defender who has been playing for PEC Zwolle this season. Sandler has played for most part of his youth for Ajax, but was eventually signed off for unspecified reasons.
He has developed himself spectularly this season, and is being compared to Van Dijk with his playing style. Extremely accurating in his passing and quite mature in his playing.
This news comes as a shock in the Netherlands though because both AZ and PSV were trying to sign him this transfer period.
He is being regarded as one of Holland's most talented defender at the moment.
