Everton boss Marco Silva insists he's not unsettled by a tapping up probe for when he was with Watford.

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.

"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."
