The left back who has played at all youth levels for Holland is one to watch, and links have already been made with a loan move last year of Tom Cleverly.
Martnez was happy to have signed the full back, who will provide cover for Maynor Figeroua.

"Technically he is very gifted, very comfortable in possession and physically, he uses his intensity to defend very effectively.
He can play left-back or left wing-back and without a doubt he's got a phenomenal career ahead of him.
We rate Patrick really highly and his professionalism and his personal attributes will be a huge asset to us this season.
Like Tom Cleverley (on loan from Manchester United) last year he is a young player who is hungry to learn his trade and I feel both parties can benefit hugely from the move."
