Marco Silva insists the independent investigation into Everton's alleged tapping-up of him when he was Watford manager is "not important".

The Premier League has asked a law firm to launch an inquiry into whether the Toffees made an illegal approach for the Portuguese last season.

Everton wanted Silva to be Ronald Koeman's replacement after the Dutchman was sacked last October, but, despite an approach to Watford, including the offer of around €11.2m in compensation, they were denied permission to speak to their primary target.

Silva was eventually sacked in January after results took a nosedive, allowing Everton to appoint him at the end of the campaign after bringing Sam Allardyce's short-lived reign to an end.

Watford issued a statement claiming the catalyst for their drop-off in results was Everton's approach which "jeopardised" the long-term future of the club.

The Hornets complained to the Premier League and, despite its attempts to mediate, and the €45m transfer of Richarlison from Vicarage Road to Goodison Park, there has been no resolution to the dispute.

"I don't have thoughts about the situation," said Silva.

"I don't lose my focus, I am really calm with the situation and my focus is on what is important for me and for us as a club and it is the next game.

"I've been working here since July 3 to prepare our squad for the matches and training sessions.

"I don't hear anything. It is not important for us and for me as a manager, for our players or for us as a club."

Everton do not view the latest development as particularly significant.

Instead, they see it as the next step in the process towards a satisfactory conclusion for all parties.

The investigation is expected to take several months and if it suggests Everton do have a case to answer, the league would then appoint a QC-led commission which would have the power to impose a large fine.

However, the imposition of a points deduction, which is the most severe sanction, would be unprecedented and highly unlikely.

Everton have also become involved in a second tapping up row dating back to 2016 relating to a former Cardiff City youngster.

It is claimed the club breached regulations on the transfer of minors when attempting to sign the under-16 player.

"Everton has been notified of an allegation relating to an approach by the club to an academy-aged player," said a club statement.

"On being made aware of this, we immediately launched an internal investigation and have been co-operating fully with all of the relevant authorities."
