Manchester United were beaten for the second time in as many games as Feyenoord won Thursday's Europa League contest 1-0 at De Kuip.
Tonny Vilhena proved Feyenoord's hero as they upset Manchester United to win their Europa League Group A opener 1-0 at De Kuip on Thursday.
In a lacklustre encounter in Rotterdam it was the hosts that earned a big three points through Vilhena's 79th minute goal, despite suspicions of offside in the build-up.
The defeat marks further disappointment for United after last weekend's 2-1 derby defeat to Manchester City, which marked their first competitive loss under Jose Mourinho.
