Tony Pulis: Selhurst Park reign appears to be over.

Crystal Palace manager Tony Pulis has left his role after talks with co-chairman Steve Parish in London on Thursday evening, Sky sources understand.

Pulis oversaw training, as well as the signing of Liverpool defender Martin Kelly, earlier in the day but is then believed to have travelled to a central London hotel for a meeting with Parish.

The former Stoke boss was reportedly at odds with the club's board over their dealings in the transfer market this summer, having missed out on several of his top targets including Gylfi Sigurdsson and Steven Caulker.

He has managed to complete the signings of Kelly, Brede Hangeland and Frazier Campbell, but it appears Pulis was not happy with his squad just two days before they kick off the season against Arsenal - Keith Millen is expected to take charge at the Emirates.

Palace have been linked with a move to bring their former winger Wilfried Zaha back to Selhurst Park after a difficult first year at Manchester United.

Speaking to Sky Sports News on Tuesday, Parish insisted that Pulis would be given all the support he needed to build the squad he wants.

"It's up to the manager, the players we sign. It's not up to me. I'm there to help him get the squad he wants," Parish said.

"There's a sentimental value and I loved Wilf as a kid and he did sensational things for us.

PALACE CONTENDERS We look at some of the candidates to succeed Tony Pulis. MALKY MACKAY Out of football since leaving Cardiff last season, Mackay is highly rated by many in the game and has close ties to Palace sporting director Iain Moody. NEIL LENNON Former Celtic manager Lennon is keen to land a top job in England. After winning three successive Scottish league titles, the Selhurst Park job would be an entirely different kind of challenge. DAVID MOYES Could the former Everton and Manchester United boss be tempted by a swift Premier League return? KEITH MILLEN The former Bristol City manager has been serving as number two to Pulis. Has no Premier League management experience so it would be a gamble were Palace to plump for the 47-year-old. TIM SHERWOOD Cut his teeth as a manager at Tottenham last season, and was certainly not afraid of speaking his mind, which rubbed some up the wrong way. He is keen to get back into work and at the top level.

"I know the fans would like him back and that will play a part, but in the end the manager will decide what we do."

But the latest developments are a devastating blow for Palace considering how Pulis transformed the club's fortunes when he was brought in to succeed Ian Holloway last season.

The Eagles had won only one of their opening 11 Premier League fixtures when Pulis arrived towards the end of November, but the former Stoke boss soon steered the club away from the relegation zone.

Palace won three of his first four games in charge, and a superb run of five consecutive wins over March and April ensured top-flight football for this season.

An 11th-place finish was the club's highest finish since the launch of the Premier League in 1992, and Pulis had hoped to build on that achievement over the summer.

But a lack of transfer funds apparently caused rows behind the scenes, and his future appears to lie elsewhere just 48 hours before the start of the new Premier League season.

Speculation has already opened into who might take over from Pulis with Malky Mackay, Neil Lennon and Steve Clarke prominent in the early betting.

Palace have confirmed they will hold a press conference on Friday at 3pm, when Parish is expected to clarify the situation regarding the departure of Pulis.
