While signing Digne represents a giant leap forward for Everton and their squad, they are still some way of being able to compete with the top sides in the division.
The French left-back was linked with a move away from Barcelona in the past few weeks.
Anyway, Digne has called Everton a "big club" with "great history" ahead of donning the blue shirt in the new season. "That is what is important and I could not be more excited about this challenge".
Immediately I said: 'I want to come to Everton'.
The France global, 25, has put pen to paper on a five-year contract at Goodison Park and will compete with Leighton Baines for a place in the Toffees first-team.
Digne, who has 21 caps for his country, spent the last two years at Camp Nou after spells at Lille, Paris Saint-Germain and Roma.More news: Indian central bank raises rates for second time

The summer transfer window shuts for Premier League clubs on Thursday 9 August with the new top-flight season starting a day later.
Could it just be a coincidence that Liverpool's club slogan is "You'll Never Walk Alone"?
You can bet that Liverpool fans will remind Digne of his tattoo when Liverpool meet Everton at Anfield on December 1.
The 25 year old also revealed that manager Marco Silva was pivotal to his signing, and said that his first impressions had been good.
Digne comes to Everton having already won two league titles in France, with PSG, and a La Liga and Copa Del Rey double with Barcelona last season.
"Lucas is a player who will bring competitiveness in the right back position for us".
He becomes Everton's second signing of the season after Richarlison, who arrived from Watford for a reported £50m fee.
