The 22-year-old joined the club on transfer deadline day and claims it was always his ambition to play football in England, but he is aware that he must acclimate himself to his new surroundings in order to make an impact.
"It was a dream to play here," he told the Liverpool Echo. "As a young boy I wanted to come to England and play. There were other clubs who were interested in me but it's not important now. I'm happy here and it was the best decision for me."
The Costa Rica international has compared himself to Everton players Leighton Baines and Steven Pienaar, but realizes getting in the first team will be a long-term challenge."The left side for Everton is very good," he said. "Baines and Pienaar play very well and have played together for a long time. I can be there also but I'll need to play well to have a chance."
The former FC Copenhagen man started Everton's third-round League Cup tie against Leeds, with the Toffees losing 2-1 to the Championship side.
"It was a difficult game against Leeds because we did not play well in the first 20 minutes and the first half was not great," he said. "We needed to be more aggressive and concentrate better."
