It is a very good deal for Watford, it is a lot of money for a young player, circa 35m as I understand it. In twelve months to two years he could be worth 10m or 80m and that is the risk being taken by both clubs.Find one Watford fan who thinks anything other than this is a ludicrously good deal for us. Deulefeo single handedly taking Chelsea apart this year (subbed after 89 minutes, mind) showed us what potential is.
Don't forget we know Deulofeu even better than ye do. With all due respects to Watford if you look at the clubs he has already played for it is hardly a career in an upward spiral , although he is still relatively young. Most of us loved him at Everton but recognised he would not be part of a top team because of his lack of application regarding the defensive side of his game.
If we had bid instead that level of money for Deulofeu I somehow think he would be at Finch Farm at the moment. A talented player but flawed.
