Gerard Deulofeu represented Everton on loan during the 2013-14 campaign, before moving to the Toffees on a permanent deal in 2015.
Deulofeu scored four times in 33 appearances for the Merseyside outfit during the 2015-16 season, before making a further 11 appearances in the first half of the 2016-17 campaign.
Deulofeu was sent on loan to AC Milan for the second half of that particular season, however, before Barcelona re-signed him in the summer of 2017.
The Spaniard only spent another six months at Barcelona, however, before moving to Watford on loan for the second half of the 2017-18 campaign.
Deulofeu then moved permanently to Watford during the summer, but is yet to feature for the Hornets this season due to injury.
The 24-year-old opened his Watford account against Chelsea last season, however, and will now be looking to kick on at Vicarage Road.
The Everton fans want him back, however, and have called for that to occur. A selection of the Twitter reaction can be seen below:
