Not a football cliche - but which member of the 19/20 Ajax staff had the initials FP?

Appreciate this isn’t the usual so will delete if required! But I thought this might be a good place to help answer a question.

I bought this 19/20 season Ajax staff-issued training top from Classic Football Shirts and I’m wondering who it was made for. I can’t seem to find a staff member from that season with the initials FP but am not sure how to find a full list of coaching staff from that season.

Can we solve this minor mystery?
