Sam Allardyce has revealed Crystal Palace have failed in attempts to sign 'about 20 players' during the January transfer window.

The Palace boss landed Jeffrey Schlupp from Leicester earlier in the window, but has since struggled to get new signings over the line.

The Eagles agreed a deal with Arsenal for full-back Carl Jenkinson, but reports yesterday claimed the proposed transfer across London was off because terms could not be agreed.

Palace have also been linked with a host of other names including Patrick Van Aanholt, who Allardyce worked with at Sunderland last season, Patrice Evra and Jose Fonte.

But the Palace boss did not appear ready to give up in the race to prise Jenkinson away from Arsenal.

"Until the chairman rings me up and says Carl Jenkinson deal is dead, it's still ongoing for me," said Allardyce.

"The same with Van Aanholt - we're interested."

Allardyce declared Schlupp fit for Saturday's visit of Everton, but conceded he had hoped to have more reinforcements by this stage in the winter transfer window.

He added: "We've got one signing, but missed about 20.

"We missed one yesterday in Jake Livermore. Not much success so far. We were in the race and we didn't win that race."

Asked if Palace were attempting to sign former defender Fonte, Allardyce responded: "We're in the race for many."
