Derby were probably still reflecting on how that opener came against the run of play when Will Hughes rattled in a second two minutes later. The midfielder will have secretly enjoyed that one against his former club, especially the way it rattled into the bottom corner, but a large dose of the credit should go to the tireless Tom Cleverley who not only prevented a Derby counter with a smothering block in the face of four Derby players, but also set up the chance for Nathaniel Chalobah to back heel it to Hughes.
Like against Bristol City, it would have been more. From a rich supply line down the right, Femenía flashed one across the face that Chalobah and João Pedro, both at full stretch, just missed and then Sarr put over an even more teasing ball at the end of the half that saw João Pedro end up in the net but, somehow, not the ball.
The Hornets ended the half in complete control and largely untroubled, apart from one Martin Waghorn looped onto the bar and one Colin Kazim-Richards had ruled out for a foul by Andre Wisdom from a corner.
