Manchester United fans were keeping a keen eye on Europa League action on Thursday evening as Arsenal faced Napoli.
That's because transfer target Kalidou Koulibaly was playing against the Gunners in the Europa League quarter-finals.
Arsenal had won the first leg at home 2-0 and they kept their European form going with a 1-0 victory in Italy.
Koulibaly struggled at the Emirates first time around but started brightly against Arsenal in the reverse leg.
The 27-year-old has been linked with a move to Old Trafford this summer and many Manchester United fans took another opportunity on Thursday evening to analyse his performance.

Koulibaly was by no means exposed during the second leg but was far from impressive, with supporters all saying the same thing about his performance.
It seems his reported transfer value is a big sticking point for many supporters as the summer transfer window edges closer.
