• Two men filmed making plane gestures during Cardiff game
• Fan behaviour back in spotlight after four arrests at Watford

Police have detained two Southampton fans who appeared to mock the death of the Cardiff striker Emiliano Sala, on a day when unrelated incidents put fan disorder back in the spotlight.

At St Mary’s, two men were filmed apparently making plane gestures during Southampton’s defeat to Cardiff in reference to the crash which killed Sala and left the light aircraft’s pilot, David Ibbotson, missing.
