Ever Banega has been presented to the media after undergoing a medical at Sevilla.
The club reached an agreement with La Liga rivals Valencia over the transfer of the Argentina international on Sunday, with the 26-year-old having a medical with the club on Tuesday.
Banega had been at the Mestalla since 2008 but spent last term on loan at Newell s Old Boys in his homeland, featuring 20 times in all competitions and scoring once.
He also spent a season on loan at Atletico Madrid during his time with Valencia, but revealed he was looking forward to joining up with former boss Unai Emery at Sevilla.
I want to work every day to earn a place and repay the trust that this club has given me, he said.
Valencia is already past. I appreciate all that happened there, but now I have to focus on my new club.
Fellow new arrival Gerard Deulofeu on a season-long loan from Barcelona is also looking forward to playing alongside his new team-mates.
[I am] Very happy to be here, he added. [Barcelona coach] Luis Enrique told me that I would not have minutes and from the first moment I had in my mind to come to Sevilla.
It is a very good club that has high expectations and hopefully we can make a great year together.
Sevilla, last season s UEFA Europa League winners, have been active in the transfer market during the close-season, with Banega the eighth arrival as Emery looks to cope with the losses of Ivan Rakitic and Alberto Moreno, who have joined Barcelona and Liverpool respectively.
