Morgan Schneiderlin has been reunited with former manager Ronald Koeman after signing a four-a-half-year contract at Everton.
The France international moves from Manchester United for an initial fee of Â£20million, rising to Â£24million, to link up with Koeman again having spent one season at Southampton with him.
"I'm very pleased because I know the player, I know the qualities of the player, I know him as a person and he's really desperate to come to Everton - and that's what we need," said Koeman.
"He's a strong character. I worked with him for one season at Southampton and he's a midfield player who can play in different positions in the midfield. He's also a fast player, he's a clever player and he's a personality. Normally, he's part of the French national team and at 27 years old he's part of the future at Everton.
"We want good players but we also want players who really want to show their qualities in front of the fans of Everton."
Schneiderlin moved to Old Trafford for Â£25million in the summer of 2015 but after one season under Louis van Gaal he fell out of favour when Jose Mourinho took over for the current campaign,
The 27-year-old has made just eight appearances under the Portuguese, and only three in the Premier League as a substitute, and Koeman is hopeful the move to Goodison Park will bring out the best in the midfielder as he puts his Mourinho nightmare behind him.
"Morgan is really hungry to show his qualities and to play because that is the best thing for a football player," said the Dutchman.
"You are born as a football player to play games, not to sit on the bench or not be part of the team.
"But this is a new step, it's a new future and he will show his qualities. I am convinced of that."
Schneiderlin said he wanted to move to "a club with big ambition and great expectations, to come in every day and work for something that you want to achieve because that's what drives you forward", insisting he is "hungry as ever and (ready) to eat football again".
"There is a manager in place here that I know, I know he can get the best out of me, I know his style and how he likes to play football," he said.
"He was very good with me from the start and I enjoyed playing football under him.
"He was very good for me and, obviously, he was a massive player in his playing days and you can only learn from the best.
"At Southampton he gave me some great advice to keep improving every day and it was a pleasure to work with him.
"We spoke since the time I knew Everton would be interested. I know his ambition and why he came here.
"He believes in this and I do, too. We are trying to achieve something here and this is what I am here for.
"I just want to play football. I want to put my print on this club and do everything to get Everton where it belongs.
"I know the fans have big expectations and we'll do everything to make them come true."
