The first thing Vincenzo Montella did when he took over Sevilla in January was put Steven Nzonzi back in the team.
The former Blackburn and Stoke midfielder who had been a revelation at Sevilla until falling out with the previous coach paid his Italian manager back with interest on Tuesday night at Old Trafford.
The only problem for Sevilla now is that he will be back on the radar of most of Europe's big clubs after one of the best performances of the last-16.
Sevilla had everything United lacked because they had Nzonzi.
