Everton are heavily linked with the Barcelona star this summer.
The Toffees are heavily linked with a move for Digne and The Daily Mail reported on Monday that Everton's Director of Football Marcel Brands had flown out to Catalunya to try and secure an £18 million transfer.
Silva and Brands completed their first signing of the summer on Tuesday after Richarlison joined the Goodison Park side for a reported £40 million.
And the Portuguese manager confirms that the Merseyside club are 'trying' to follow that one up by signing the French defender.
He told The Star: "Digne is not at the club he is at by luck. This will not be easy, but we will try."
The talented left-back, who earns £55,000 per week with the Primera Division giants [Silly Season], would be an excellent signing and one who would surely displace Leighton Baines.
Baines has been a fantastic servant for Everton down the years, but he turns 34 in December and Silva is right to be plotting his successor.
