Everton have signed Manchester United midfielder Morgan Schneiderlin for a fee rising to £24m.
Schneiderlin, 27, has signed a four-and-a-half-year contract to link up again with Toffees boss Ronald Koeman, whom he played for at Southampton.
The France international played 47 times for the Red Devils following his £25m move from the Saints in July 2015.
Schneiderlin, who moves for an initial £20m, said he was "hungry as ever and ready to eat football again".
He has made eight appearances since Jose Mourinho was appointed United boss in the summer, but has only played for 11 minutes in the Premier League.
Schneiderlin's last appearance for the club came in the 1-1 draw against Arsenal in November.
He said: "Everton is a big club in the history of English football. I have always loved the atmosphere in the stadium. I can't wait to play and to represent this great club.
"There is a manager in place here that I know and he can get the best out of me. I know his style and how he likes to play football. He was very good with me from the start and I enjoyed playing football under him."
Koeman demanded the club make signings this month after their FA Cup third-round defeat by Leicester.
Midfielder Tom Cleverley has left to join fellow Premier League side Watford on loan for the rest of the season, with an option to buy.

Morgan Schneiderlin has struggled to adapt and stamp his personality on anything at Old Trafford. But he gets across the ground well, he can tackle and he gets up and down the pitch.
At his best he's a typical Premier League central midfield player. Everton are buying someone who you know has been able to produce the goods in the Premier League from his time at Southampton. He's not a gamble.
