Watford's Andre Gray scored a stoppage-time winner as Leicester City began life under new boss Brendan Rodgers in underwhelming fashion, suffering a 2-1 defeat at his former club in the Premier League on Sunday.
Watford clinched victory in the second minute of added time as Troy Deeney latched on to a poor goal kick by Leicester keeper Kasper Schmeichel and fed substitute Gray who held his nerve to score.
The home side had taken the lead through Deeney in the fifth minute as the striker got his body across Wes Morgan and rose well to head home Gerard Deulofeu's whipped ball from a free kick for his first goal in 10 matches at Vicarage Road.
