The former Liverpool star was a key figure in midfield for the Dutch club who edged his old rivals 1-0 in their opening Europa League fixture at De Kuip in Rotterdam.
Tonny Vilhena scored the only goal of the encounter in the 79th minute to help Feyenoord pull off a surprise result over Jose Mourinho's men, prompting a satisfied reaction from 36-year-old Kuyt who had many battles with United during his days at Anfield.
