Chelsea will have to shell out £20 MILLION to sack manager Andre Villas-Boas. The Sun says the under-fire Chelsea boss still has 2½ years to run on his £150,000-a- week deal.

It was only five months ago Blues owner Abramovich paid £13.3m in compensation to land the Portuguese.

That means the cost of his reign - if cut short - will be more than £33m.

Villas-Boas, 34, thinks he is safe as he does not believe Red Rom will want to pay him off.

But AVB is under huge pressure after Sunday's 2-1 home defeat by Liverpool - a fourth defeat in 12 Prem League games. They are now 12 points behind leaders Manchester City.
