Frank de Boer has called on referees to provide more protection for Crystal Palace's Wilfried Zaha after seeing the winger endure a rough ride against West Bromwich Albion in the Premier League Asia Trophy on Saturday.
Zaha faced a difficult evening against Tony Pulis's side as Palace ran out 2-0 winners in the third-place playoff thanks to a curling free kick by Luka Milivojevic and a deflected effort from Bakary Sako, with both goals coming in the first half.
"If you want to sell the Premier League here and the beauty of the game, the beauty of the game is not those kind of challenges," said manager De Boer.
"Of course, when it's a fair challenge then for me it's not a problem, but for example for Wilf Zaha they were really looking for him, to injure him, and we can't accept that. No manager can accept that.
"He's one of the exciting players of the Premier League. I don't want to think that he's out for a couple of weeks or months.
