In their first game since the pause to the season due to coronavirus, Marcelo Bielsa's side knew that a victory would establish a ten-point cushion in the division's automatic promotion places and also send them back into top spot above West Brom.
Yet goals from Junior Hoilett and Robert Glatzel gave the Bluebirds a 2-0 victory.

6 Industrious first half, looked very frustrated in the second. Found little joy in the final third
8. Helder Costa
5 Heavily involved in the first half but unable to create. Ineffective in the second half, kept trying but was replaced
9. Tyler Roberts
6 Looked sharp in the first half, made some clever contributions, had one good chance in the second half and was foiled. Faded, physically, late on. Picture by David Davies/PA Wire.

11. Patrick Bamford
5 - Struggled to make much of an impact, got in the way of a goalbound shot. Unable to convert other half chances
