Crystal Palace are still waiting for Luka Milivojevic to finalise a visa one week after his £13million move from Olympiakos.

The 25-year-old Serbia international cannot make his debut until his visa comes through and the delay is frustrating manager Sam Allardyce.

The midfielder left London within hours of his deadline day transfer to sort the documents and is yet to return. There are not thought to be any problems with his application but it is unclear whether the process will be completed in time for Milivojevic to play against Stoke on Saturday.

Allardyce needs Milivojevic to make an impact with Palace in the relegation zone after their 4-0 defeat to Sunderland. “He will bring a bit of stability into midfield,” said Allardyce. “You can get through it too easily at times. You saw that against Sunderland.”

Responding to jeers from the Palace fans following the 4-0 home defeat to Sunderland, Allardyce added: “It’s an emotional game and fans get very emotional when they see us turn out the sort of performance we did.

“We don’t want them to react like that but in many ways you can understand it. Fans will show their disapproval when they’ve paid their money – not that way. The booing I expected, and rightly so. But they shouldn’t be jumping over on to the pitch and confronting a player.”
