Crystal Palace manager Alan Pardew says he hopes to see more from Wilfried Zaha after an underwhelming performance in the 1-0 defeat to Tottenham Hotspur.
Spurs new-boy Son Heung-min netted the only goal of the game at White Hart Lane on Saturday to give the hosts a hard-fought 1-0 win over Pardew's side, who have now lost two in a row.
Starting his sixth game of the campaign, Zaha was replaced by Fraizer Campbell at half-time and Pardew admits the England international was substituted because he was not up to standard during the first 45 minutes.
"I didn't think Wilfried played well so I took him off," Pardew said in his post-match press conference.
"The issue with Wilfried is that he's a fabulous footballer, and I'm trying to get him to understand that every game is very important.
"It's about concentration and having that same desire to defend, to attack, for movement and everything that a top player produces, and unfortunately today I don't think he did that.
"He had 45 minutes to show me that he was up to speed in those areas and he wasn't, so therefore he needs to take that as a lesson. He's not the first player who didn't do their job."
