Ivan Rakitic was once a transfer target at Manchester United - but he will now be out to inflict misery on them on Thursday night.
Had things gone Jose Mourinho's way, there's every chance Rakitic would have been lining up donning the red of United and pulling the strings in the middle of the park alongside the likes of Bruno Fernandes and Casemiro, rather than against them.
Back when the self-proclaimed 'special one' was at the helm of the Red Devils, Mourinho was keen on the idea of securing Rakitic's signature while the midfielder was still plying his trade at Barcelona.
