Manchester City manager Pep Guardiola says that "pure logic" suggests Marc Guehi should be allowed to play in the Carabao Cup final against Arsenal.
Yet the centre-back will be blocked from playing at Wembley on 22 March because he is cup-tied after appearing three times for previous club Crystal Palace earlier in the competition.
But it is not quite as straightforward as that.
Because it was only this season that the EFL relaxed its cup-tied rules to allow a player to feature for two clubs.
And the 25-year-old has fallen foul of a clause which required him to sign for City before the first leg of the 5-1 aggregate semi-final victory against Newcastle.
