1.He was a Manchester United player between 2011-2015, during which time he only made two appearances for them. One in the league against Sunderland and one in the famous and much-criticised 4-0 defeat in the Capital One Cup against Milton Keynes under Louis van Gaal.
2. During his time as a Manchester United player, he was sent out on loan to Leicester, Derby, Blackburn and...Burnley. Who he of course ended up signing for on a permanent basis in January 2015.
3. Due to his Irish ancestry, Keane, like fellow Keanes Robbie and Roy, represented the Republic of Ireland. But only at U17 and U19 level before deciding 2012 that he'd rather represent England from thereon. He's since made two appearances for the England senior team, his debut being in a defeat to Germany in as friendly in March 2017.
4. He made the 2015-16 Championship team of the year whilst playing for Burnley.
5. He scored seven goals during his time at Burnley, including two last year whilst in the Premier League. In the season before that, he scored five in 44 matches as Burnley were promoted to the Premier League.
6. His twin brother Will, a forward, was also at Manchester United as a youth team player and also made exactly two appearances for the Reds. Like Michael he went on a string of loan spells- Wigan, QPR, Sheffield Wednesday and Preston- before joining Hull on a permanent basis in August 2016. He made just five appearances for them last season, without scoring a goal. They're the exact same height at 1.88m.
7. Even though figures are rarely exact when it comes to big transfers, he's though to be the third most expensive signing in Everton's history at 24.23 million. Only Romelu Lukaku (30 million) and Yannick Bolasie (24.5) cost more than him.
8. The 'whoscored.com' website lists his strengths as aerial duels, blocking the ball and concentration though bizarrely highlight his tackling as 'weak', Hardly a ringing endorsement for a central defender.
9. He considered the presence of Ronald Koeman as Everton manager, a world-class central defender in his time of course, as the main reason why he opted for the Toffees rather than the likes of Liverpool or Manchester United.
10. His new side Everton are [3.25] for a Top 6 finish. He'll be competing with the likes of club captain Phil Jagielka, Ashley Williams, Ramino Funes Mori and young starlet Mason Holgate for a place in the starting XI.
