Crystal Palace manager Alan Pardew fears Connor Wickham may not be available for Sunday's Premier League showdown with Liverpool. Wickham has taken on the responsibility of finding the back of the net for his side in recent weeks, scoring four in his last two appearances having previously struck just once all season.

Palace are without a league win in 11 games but have dominated their recent meetings with Liverpool, having beaten the Reds in their last three league encounters and effectively ened their Premier League title hopes in a thrilling draw in the 2013-14 season. But if they are to continue that run of form against the Merseyside club they may have to do it without Wickham.

"Connor has done terrific. Unfortunately he's got a knock that we are going to have to have scanned today that he picked up in the game," Pardew told a press conference. "We wasn't sure if it was just a little bang but it might be a bit more serious than that. But we are going to have to check him out today. He's probably touch and go for Sunday."

Pardew could also be without first choice goal keeper Wayne Hennessey. The former West Ham United and Southampton boss has both Alex McCarthy and Julian Speroni in reserve, but will make a late decision on who starts in goal. Left-back Papa Soare is fit once again however with Pardew confirming he will be given starting role at Selhurst Park.

"Wayne Hennessey is also struggling. That is something we will have to look at in the 11th hour as well. Pape Soare is back on that left side, which is important. He will start.

"We can't look at the past [vs Liverpool], because we're in different places. Our form was very good at the end of last year. That's not to say we haven't still got players who can worry their defenders. Wilf and Bolasie have enjoyed playing them in the past."
