Watford's pre-season friendly with Europa League winners Sevilla has been brought forward by a day and will now be played on Friday, July 31.

The game against Unai Emery's men had originally been scheduled for Saturday, August 1.

But it will instead be played a day earlier (kick-off 7.45pm), though no reason has been given for the switch.

Sevilla won the 2014/15 Europa League by overcoming Ukrainian side Dnipro 3-2 at the end of May - their record fourth triumph in the competition.
