Winning debut for Swansea boss Carlos Carvalhal as late goals down Watford

Ayew struck an 85th-minute equaliser and substitute Narsingh netted a 90th-minute winner for Swansea after Peru forward Andre Carrillo gave Watford an 11th-minute lead with a close-range header after visiting keeper Lukasz Fabianski could only parry Richarlison's fierce shot from a tight angle.

It was the most unlikely climax to the match as Watford dominated and looked set to celebrate their second successive league win, with Swansea looking bereft of ideas after Ayew's fifth-minute piledriver from 30 metres hit the crossbar.

However, Watford were punished after substitute Andre Gray missed a sitter moments before Ayew's equaliser and Narsingh stunned the home crowd as he swept home a rebound to give Swansea only their second league win in 13 games.
