Crystal Palace manager Patrick Vieira has admitted he is "disappointed" for Conor Gallagher as he is unavailable for their FA Cup semi-final with Chelsea.

The Blues had the final call on whether or not the midfielder could feature in the game as they are his parent club, and the decision was made that he would not be allowed.

The England international has been a vital part of the Palace team this season, featuring in 31 games and scoring eight goals in all competitions.

Despite the fact he has played in all of the FA Cup games so far, Gallagher will not be part of the semi-final, much to the frustration of his boss.

"It is an experience the player is missing and I am disappointed for him. He has played all the games so far and if there is somebody who deserves to be in the semi-final, it is him because of his performances, so I am disappointed he will not be able to play," Vieira told reporters.

"Since he has been with us, he has been fantastic, and for him not to have a chance to get involved in that game, it is something frustrating for his development. I feel for him because he wanted to play in that game, every player would want to play in that game."

The Eagles will meet Chelsea at Wembley on Sunday, April 17 with a place in the final against either Liverpool or Manchester City on the line.
