The French Under-21 international forward moved to Goodison in the summer after rejecting a number of clubs when he left Strasbourg.
Now Gueye has revealed that coach David Moyes has huge belief in him.
"I am someone very ambitious, I have always dreamt to play in a great league, it has always been in my mind," he said.
"I know it will be difficult at Everton, I will have to work hard to get a position in the team, but it is the very best for me."
Gueye revealed that Moyes feels that he could be his 'secret weapon'.
"The coach was following me for six months. He wants me to succeed to play like Steven Pienaar," he said.
"He even said I am his 'secret weapon'. I am always in the group, the coach will feel the right moment to play me."
