An office that measures 20 yards by six yards may sound quite spacious to many people, but when you’re a football it is quite a confined space that you generally have to share with other people.

When Mileta Rajovic arrived at Vicarage Road a little over a year ago he described the six-yard box as his ‘office’, and while he's had his ups and downs in the 12 months since it’s hard to deny that when someone gets the ball to him in that rectangle in front of goal he knows exactly what to do with it.

Tom Dele-Bashiru’s attempted curling shot at Millwall yesterday deflected up off a defender and the big Dane had anticipated well enough to get beyond the last defender and head it inside the back post.

Millwall looked in vain for an offside flag, but stills after the game showed Rajovic was a couple of yards onside and Lions manager Neil Harris admitted afterwards there “wasn’t much noise” in his dressing room about the goal.

“In the box, he’s different class. Around the place, he’s different class,” was how Tom Cleverley described Rajovic, whose 12th goal for the club meant he scores, on average, every 162 minutes for the Hornets.

“He thoroughly deserved that goal today because he can smell a chance out.

“That was exactly his job when he came on today and I’m really happy for him because he is someone that even when he’s left out tries to prove me wrong.

“That is the kind of environment I like.

“Mileta works hard every day. There’s no secret that Bayo’s all-round game leading up to the box is the reason why he’s in the team right now.

“In the box, Mileta has proved he is the most effective.

“It’s up those guys to improve, learn off each other and I’m sure there’ll be different games in terms of what we need.

“But I was really happy with how they both performed today.

“All I can ask of Mileta is to put his neck forward and make my team selections as difficult as possible.”

When the late goal went in, and after the final whistle, the Watford boss was in the thick of the celebrations.

“We had a couple of late ones against us last season, didn’t we?!” he reflected

“You work so hard every day for these pieces of luck, that come from things that we work on.

“It’s my first last-minute winner as a coach, and I’ve definitely aged in the last 90 minutes!

“It’s pleasing that the referee made the right call on the winning goal too, in a game where he had to make a few.

“Mileta smelt the chance, he’s taken the risk to make a run and got himself in the right position while staying onside.”
