Indeed, the Newcastle United boss is priced at 6/1 after the Magpies' 5-1 loss at Chelsea on Saturday afternoon.
Manchester United's Louis van Gaal remains the favourite to be booted out next but McClaren is now level with Norwich boss Alex Neil.
Newcastle fans appear fed up with McClaren but it's a matter of how owner Mike Ashley feels.
Meanwhile, Aston Villa boss Remi Garde remains second-favourite in the running ahead of Villa's clash with Liverpool
Sky Bet price the Frenchman at 5/1 to leave his post next.
One man who will be delighted to see his odds drift, however, is West Brom boss Tony Pulis.
Indeed, West Brom beat Everton 1-0 on Saturday afternoon to put some distance between the Baggies and the relegation zone. And Pulis's odds have lengthened as a result.
Who will be the first to go - Van Gaal at Manchester United, McClaren at Newcastle, Garde at Aston Villa, or could Pulis still go if West Brom struggle?
