Ever Banega says he turned down Everton as he still had things to learn in Spain.
The Argentine international was a target for The Toffees during the window, and they even went as far as getting a work permit approved for him.
But he instead opted to stay with Valencia, where he has started the season in the first-team.
"I feel that I am more mature now and that I still have many things to learn and show in Spain, that's why I decided not be transferred to the English league," said Banega - who spent last term on loan at
Atletico Madrid.
"It was me who didn't want to leave, I wanted to continue because I think in having a place in the team and I want to continue in that way.
"Besides what is said about me, I think about my team and about being a good team mate, look at the unity that our team showed last weekend on the pitch and I hope that it all continues in this way.
"You must know when you can do certain things and when you can't. Thanks to the support of important players I am more mature, I am learning many new things and that's good for me and for the team."
