Pulis has grown frustrated by Palace's failure to push through deals for various players he targeted to strengthen the squad, according to a BBC report.

Several media outlets reported Pulis had entered an urgent meeting with the Palace hierarchy to discuss his dismay at the lack of signings.

Bookmakers drastically cut the odds on Pulis being the next Premier League manager to leave his post, with some closing the market due to heavy betting on the former Stoke boss, who had gone from being a 40-1 shot on Wednesday to the odds-on favourite.

Palace did not immediately respond to requests to clarify the situation.

The news of the talks emerged just 48 hours before Palace's opening Premier League match of the new season at Arsenal on Saturday.

Pulis led Palace to an impressive 11th place finish in the Premier League last season after inheriting a squad in turmoil in November.

The Welshman was named the League Managers Association's Premier League manager of the year in May.

Before reports of the meeting involving Pulis and Parish emerged, Palace clinched their fourth signing since the end of last season with the �1.5 million capture of Liverpool defender Martin Kelly.
