Holders Spain became the first team to score more than two goals in a game at Euro 2016, beating Turkey 3-0 as Andres Iniesta shone again and forward Alvaro Morata answered his critics with two goals.

Romelu Lukaku scored two goals for Everton, one demonstrating rare strength and skill, to knock his old side Chelsea out of the FA Cup 2-0 in a dramatic quarter-final featuring two red cards on Saturday.
