Sacking Allardyce and hiring Silva could reportedly cost Everton at least £18m

Why sacking Sam Allardyce and appointing Marco Silva as manager could prove to be a very expensive task for Everton.

It could prove another costly summer for Everton as their search for a new manager starts following the sacking of Sam Allardyce.

Allardyce has been dismissed just six months into an 18-month contract the 63-year-old signed when he was appointed Ronald Koeman's permanent successor on November 30.

The Guardian reports that the former England boss will be paid off the final £6m left on that deal, which along with the £3m already received will see him walk away with £9m for half a year's work.

Allardyce's backroom staff of Sammy Lee, Craig Shakespeare and Martyn Margetson will also be axed, adding to the mounting costs for majority shareholder Farhad Moshiri.

Marco Silva is now the favourite to take over at the Toffees and with the Portuguese a free agent after being sacked by Watford in January, the Merseysiders are hoping to make a swift appointment.

Yet as the Telegraph outlines, that may not be so easy and will almost certainly be another expensive task. Silva was wanted by Moshiri when Koeman was dismissed back in October and the Hornets claim illegal contact was made.

In fact the Hertfordshire club directly cited the approach as reason for Silva losing his job and with no break clause in the 40-year-old's deal at Vicarage Road, if Everton do make a move to hire him Watford can take legal action and the Premier League may be forced to intervene.

Moshiri will be keen to avoid this, of course, with a compensation payment the easiest way to do that, but with £12m having been rejected back in October it is likely to cost upwards of that to land Silva this time around.
