Amid the fall-out from that night in Barcelona, perhaps the most intriguing questions centre on the involvement of Jonny Evans.
Here was the West Bromwich Albion captain in a cohort of four stealing a taxi in the city little over 48 hours before a match.
Schooled by Sir Alex Ferguson at Manchester United, Evans has previously been known for his professionalism, but the mask slipped in the early hours of Thursday morning.
The incident came little more than two weeks after Evans failed to secure a move away from the Hawthorns, with the club seemingly sleep-walking into the Championship.
