Scott Parker’s side paid the price for a wretched first-half, where they could have no complaints with being 2-0 down at the interval.

1. Max Weiss - 6
No real chance with either goal, in fact he was let down by the men in front of him for both. Distributed well and quick off his line. Photo: Kelvin Lister-Stuttard Photo: Kelvin Lister-Stuttard
2. Oliver Sonne - 4/10
Allowed his man to drift off him for Cardiff’s first goal, which set the tone. Guilty of some careless passes in the build up. Photo: Kelvin Lister-Stuttard Photo: Kelvin Lister-Stuttard
3. Axel Tuanzebe - 5/10
Guilty of a couple of shaky moments early on, none more so than when he allowed a Cardiff player to run through on goal after his boot came off. Photo: Kelvin Lister-Stuttard Photo: Kelvin Lister-Stuttard
4. Joe Worrall - 5/10
Similar to Tuanzebe, looked a little off the pace early on but did settle on. Passing wasn’t the most convincing though. Photo: Kelvin Lister-Stuttard Photo: Kelvin Lister-Stuttard
