Valencia signed on loan on deadline day from West Ham with the option to sign on a permanent basis should he impress at Goodison Park.
“I had some options but when I heard about Everton and saw the quality of the players, nobody would say not to come here,” Valencia said.
“It is a great opportunity to come here with great team-mates and an excellent opportunity to have a great year in the Premier League.
“I got the news on the last day of the transfer market.
“I was very, very happy with the news.
“I was talking with other teams but the best option was Everton.
“This is a great club with excellent fans and I want to be on pitch with my new team-mates.
“I have enjoyed training with my new team-mates, it’s different to my last team – it is a little bit harder.”
