Frank de Boer's future is on the line today at Crystal Palace.

The Dutch manager has kicked off his Palace career with three straight defeats so far this season.

TMW says De Boer has made an ultimatum to Palace's board, demanding several high quality signings be made today. And it's claimed should Palace fail to deliver, the manager will walk.

This news comes 24 hours after it emerged Palace were already sounding out agents about finding them a replacement for De Boer.

It's claimed the board already believe they've made a mistake hiring the former Ajax and Inter Milan boss.
