Having taken the first three months of the season to register two away wins, this revitalised team now have two in the space of just four days after winning at Rotherham to add further momentum to their automatic promotion charge.

It took 15 minutes for the game earlier in the season at Vicarage Road to be decided and this one was similarly done and dusted after 26 minutes thanks to goals from Franciso Sierralta and Ismaïla Sarr. Ken Sema killed the match stone dead six minutes before half-time and then it was a question of just how much the Hornets could improve their goal difference by. It could, judging by the way things are going, come down to that at the end of the season. They ended up just adding one to the goals for column as substitute Dan Gosling and Rotherham's Freddie Ladapo traded goals inside one second-half minute.

It's now eight wins in nine and just one defeat on the road in eight. That's promotion form in anyone's book. It's not just the numbers that are catching the eye, although they are pretty impressive given no Championship side has won more matches since Xisco Muñoz took over at the end of December. The performances suggests this team are on a roll, the sort of one Graham Taylor's side had in 1999 and the one Slaviša Jokanović's side had in 2015. Not many teams will relish playing the Hornets after they followed up the arm wrestle at Cardiff with this power-play win.

It wasn't quite the stroll the scoreline suggests. Rotherham had their moments, particularly from set-pieces and balls into the box, but the fact the Hornets made it look easy was testament to how clinical they were, the determination and hunger to keep this run going and the attitude of the group. It would have been easy for the team to think they have cracked it by ending Cardiff's 11-match unbeaten run in such dramatic fashion on Saturday, but there was none of that at the New York Stadium. There was a desire to put this one to bed as early as possible and do a thoroughly professional job. Mission accomplished.

Sierralta and Sema set the tone early on. Sema took one in the midriff inside his own box while the big Chilean rose highest to flick away a corner conceded inside 60 seconds and then, more impressively, strained his neck to take one off the head of Michael Cross following a cross from the right.

Not long after, Sierralta imposed himself at the other end, leaping above his marker to power in a header from a Philip Zinckernagel cross. It was just the start the team needed as it punctured any hope the home side had of keeping it nice and tight and pinching one at the other end.

Zinckernagel was also the architect of the second, curling over a cross from the left for Sarr to crash in his ninth of the season. Zinckernagel, the Danish schemer, was picking up some lovely positions in a pocket of space on the left and it was from another cross from him that Sema scored the third. You can see why he had 18 assists to his name in Norway last season.

His value to his side of late was evidenced by the half-time concern Muñoz showed for his playmaker who was in some discomfort with a hip injury. He carried on for a bit and watched João Pedro almost make it four two minutes after the break after a surge from Sarr. Richard Wood, the Rotherham captain, pulled off a wonderful goal-saving tackle, the challenge of the match.

That was virtually Sarr's last involvement, with Muñoz withdrawing his strike weapon and his partner in crime down the right, Kiko Femeńia, after just eight minutes of the second half. It was a smart move from the Head Coach. Following a superb penalty save from Daniel Bachmann to deny Michael Smith, Muñoz showed off the strength and depth of his squad by then bringing on Carlos Sanchez and Gosling for Nathaniel Chalobah and Zinckernagel. It was very good squad management by the Spaniard.

He would have been annoyed when Ladapo scored from long range just after the second of the double changes, thus ruining the chances of an 18th clean sheet, but Gosling restored the three-goal buffer immediately by being first to react to Jamal Blackman's parry of Andre Gray's shot. Gray was annoyed with himself he didn't lash in a chance with five minutes to go to make it five, but four will do nicely, especially as it was the first time the Hornets had scored four on the road in two years. Throw in the penalty save, the early withdrawal of some key players and results elsewhere, this represented a pretty good night all around. Vamos.
