Chelsea would have to pay £20 million to relieve Andre Villas-Boas of his duties, according to reports.
The Sun claims Blues owner Roman Abramovich would face a monster bill if he wishes to wield the axe on the former Porto boss, who arrived at Stamford Bridge in June courtesy of a £13.3 million compensation bill payed to the Portuguese champions.
AVB still has two-and-a-half years left to run on his current deal, with a contract in the region of 150,000-a-week making the Chelsea boss one of the highest paid in European football, according to the report.
Pressure is undeniably mounting on the Chelsea boss after yesterday's 2-1 defeat to Liverpool, with three losses in four matches knocking the west London outfit out of the Champions League positions.
Having spent big in the summer, Villas-Boas will hope and expect time to make his mark further on the Chelsea squad, with his attacking philosophy yet to take full shape at Stamford Bridge.
After big figures were spent on Juan Mata, Romelu Lukaku and Raul Meireles in the summer transfer window, more money will be requested in the New Year as the boss looks to strengthen his squad further.
A defender is believed to be the priority, but should things fail to improve quickly, the money could be going towards a £20 million exit strategy for the current Chelsea chief.
