Everton boss Ronald Koeman admits he enjoyed Feyenoord's shock Europa League win over Manchester United.

The former Feyenoord coach still has close ties to his old club.

Koeman wrote for De Telegraaf: "I've been having fun watching Feyenoord.

"My old club played a really good European team. People whine about the many changes of Mourinho, but there were all internationals on the field. Feyenoord was tactically good and defended well.

"They made a few small chances and utilized one in an excellent way. They will see that you can get a good result against a club with much greater possibilities."
