Crystal Palace manager Alan Pardew suggests Wilfried Zaha showed a lack of eagerness at Tottenham on Sunday.
Pardew hooked the 22-year-old forward at half-time of Palace's 1-0 defeat at White Hart Lane with Fraizer Campbell coming on as his replacement.
The Eagles boss explained his decision after the match, indicating that Zaha perhaps did not try hard enough in what was a lacklustre 45 minutes from the former Manchester United man.
"I didn't think Wilf played very well to be honest," he said.
"The issue with Wilf is that he is a fabulous footballer. I am trying to get him to understand that every game, every moment in every game, is very, very important.
"It is about concentration, and having that same desire, to defend, to attack, movement and everything, that top players produce.
"He had 45 minutes to show me he was up to speed on all of those areas. And he wasn't. So therefore he needs to take that away and be a lesson.
"He's not the first player, by any stretch of the imagination, who didn't do their job. He was perhaps unlucky to be taken off, because one or two others were just below their level. But he was probably the worst of the pack."
