Everton have announced their second signing of the summer, with former loanee Gerard Deulofeu set to rejoin the club from Barcelona.
The 21 year old spent the entire 2013/14 season at Goodison Park and will return on a three-year contract from 1 July, with the option of a further year, in a deal confirmed to be worth €6m (£4.2m, €6.7m).
"We are getting an even more mature player now than he was a couple of seasons ago and a player who considers Everton as home," manager Roberto Martinez told the club's official website.
"This is why we are incredibly excited to have him back on a permanent basis and to encourage him to grow, develop and mature his enormous talent."
As revealed by Barcelona, the arrangement also includes a release clause for the La Liga champions to buy Deulofeu back if an offer is made that meets a specific criteria, while they also have first refusal in the event that Everton choose to sell.
Having struggled to impose himself at the Nou Camp, the Spain international won the Europa League with Sevilla last term but is evidently delighted to be back at Everton. He tweeted: "I'm back! Once a blue, always a blue!"
"It was always our intention to work extremely hard behind the scenes to get some really good business done early on during the transfer window," Martinez added.
"Our objective was to secure Tom and Gerard as quickly as we could and I'm really pleased this is exactly what we've done.
"Having done this now, we will have more time over the remainder of the window to carry on strengthening our squad, which is already strong, and we will use this time ahead of us well."
