Roy Hodgson admits Christian Benteke's current form is a concern and says Crystal Palace cannot afford to carry a striker that is not scoring, reports Sky Sports.
The Belgian has not scored since May and missed an injury-time penalty against Bournemouth last weekend that could have won Palace the match.
"Of course when your front player - the man who is a pivotal focal point in your attack - is not scoring, it's a concern.
"It's a concern to him, it's a concern to us and it's a concern to fans.
"He can do nothing more than keep working at it, keep working very, very hard."
The Belgian cost over £30m when he signed from Liverpool in August 2016, and Hodgson warned Benteke that Palace can't afford to carry him.
He said: "If the goals aren't coming he needs to be making certain he's making a good contribution to the team's play, both in terms of our attacking and our defensive play.
"We certainly can't afford to carry anybody, let alone carry a goalscorer that isn't scoring goals."
