Tottenham Hotspur's 3-2 defeat away to Everton was their fifth loss in their last six Premier League matches leaving boss Ange Postecoglou under serious pressure.
Postecoglou was the 5/4 favourite to be the next Premier League manager to leave their job ahead of the match.
He is now as short as 4/11 with some bookies, with rumours circulating that Spurs have drawn up a short list of three possible replacements for Postecoglou.
The defeat at Everton was Tottenham's 12th league defeat of the season. It leaves the Lilywhites 15th in the table with 24 points from 22 matches.
Next up for the north London club is a Europa League clash against Hoffenheim in Germany on Thursday.
In the Premier League, Spurs will seek to end their winless run when they host relegation-threatened Leicester City at the Tottenham Hotspur Stadium on Sunday.
