Christian Benteke has been warned not to allow his desire to prove a point to Liverpool to affect his focus when Crystal Palace visit Anfield.
Tomorrow's fixture represents the striker's first there since his £27 million summer transfer ended a miserable 12 months in which he struggled to establish himself despite joining for £32.5 million from Aston Villa.
Following Jurgen Klopp's appointment as Brendan Rodgers' successor, Benteke became a peripheral figure who only appeared as a substitute during the Europa League final and completely missed the final of the Capital One Cup.
Allardyce's arrival at Palace has since taken him close to rediscovering the confidence and form with which he impressed at Villa, becoming crucial in their bid for survival, and it is that the manager does not want him to become distracted from.
Victory tomorrow would take Palace's points total to 38, which may prove enough to preserve their Premier League status, and Allardyce said: "I don't want him to get over-zealous and try to do something a bit special that may harm the team's performance.
"Trying to do that last dribble or trying to do that last flick or trick to show (Liverpool) what they might be missing. Great if it comes off, but if it doesn't it can be costly.
"If you go back to one of your old clubs you always want to show what they might be missing.
"I'd like to see him carry on playing the way he has been, certainly in the last six, seven or eight games. Since he came back from international duty, the goals are coming back.
"He's working much harder and he's creating more opportunities for himself, the players are creating more opportunities for him to score."
