Crystal Palace must move quickly to land PSV Eindhoven goalkeeper Jeroen Zoet.
The Daily Mail says Palace are facing competition from Benfica in their attempts to sign Zoet.
Zoet features prominently on Frank de Boer's list as he looks for a new No 1.
Palace have an interest in Zoet, but Benfica have now made a move for the Holland international.
The Portuguese's interest will come as a concern to De Boer, whose search for a new keeper has stalled in recent weeks.
