Watched them twice this season.
Look vulnerable at the back, especially when dealing with crossed balls into their box and defending set pieces.
Morelos will cause their back line immense trouble with his power and movement.
Look good down the right side; Karsdorp is a good players as are Berghuis, Narsingh and Tapia. Lad that played on Sunday looked good, not sure if he's a regular starter, Sinsiterra? They looked pretty quick in possession and broke fast.
No where near the Feyenoord of old but still a very solid outfit with dangerous players all over the park.
