Mackay faces exit after Tan ultimatum

London (AFP) - Cardiff City manager Malky Mackay is reportedly on the verge of leaving the Premier League club after being told to resign or face being sacked by Malaysian owner Vincent Tan.

Mackay was severely rebuked by Tan earlier this week after angering the club's supremo by asking to sign at least three players during the January transfer window.

The 41-year-old was told by Tan that he wouldn't get any new funds in the new year because he had already been handed a significant transfer kitty following Cardiff's promotion from the Championship last season.

Mackay responded by insisting he will not resign, but the BBC reported on Thursday that Tan sent the former Watford boss a letter by email on Monday, outlining his grievances at length.

Tan is said to have criticised Mackay's transfer signings, style of play and results before demanding he resign or be sacked.

A Cardiff spokesman refused to be drawn on the report, saying: "The club is not party to any letter sent from one person to another."

Mackay's position has been under scrutiny since Tan removed his head of recruitment Iain Moody in October amid suggestions of a summer transfer window overspend.

The Scot, whose contract as Cardiff's manager runs until 2016, is scheduled to hold his pre-match press conference on Friday ahead of Saturday's Premier League trip to Liverpool.
