Tonight's visit of Watford is the latest leg of a punishing schedule, ahead of a trip to Reading on Saturday, and then a well-earned break for World Cup qualifiers.

And Caldwell, who netted the second goal in the 3-1 win over Preston, admits the games can't come quick enough at present: "It's totally different when you are winning. You feel less tired, with games coming up thick and fast, because you're playing well.

"I suppose my legs are getting a little bit weary, but it's the same for everybody in the league.

"Everybody is playing Saturday/Tuesday for two or three weeks, and it's important for us that we just finish off this excellent run with another couple of great performances. That would wrap up a fantastic few weeks for us.

"It's important in this league that you split up the games into little blocks. I certainly try to do that mentally.

"This was a block of seven games, and with the Carling Cup involved, we were hoping to come through it unbeaten.

"But we are on a fantastic run and it would just be great to keep that going against Watford."

Spirit has never been an issue at the club, with a tight-knit group of players, but Caldwell feels the added belief on the back of the best unbeaten run in four years can only be of benefit: "It's obviously pleasing to be on a winning streak.

"While the confidence is up, we have to keep up the hard work, keep it going and keep winning games.

"The dressing room is not a bad place to be in at the moment. It's pretty enjoyable to be around the lads.

"We are just looking forward to Watford, and another three points and another positive result against Reading on Saturday.

"Then we'll get a bit of a break so we can re-group again.

"It's about winning another home game and hopefully we'll come through the next international break as an unbeaten side.

"That would be an excellent achievement."

Caldwell's day job is keeping the ball out of his own net, which the Clarets have managed successfully in the eight-game run, conceding only three.

But he also chipped in with only his second goal for the club on Saturday, as the side continue to prove they can score all sorts of goals from all sorts of areas: "I think our whole play has been excellent over the last few weeks.

"We've looked tight at the back. Even in the odd game over the last seven or eight games when we've lost goals – every goal you lose is a poor defensive goal, but the Forest goal was a little bit unlucky.

"Defensively, we certainly look really strong, and we're not letting teams get many chances, if any chances, and, at the other end, we're attacking well and creating some good chances for a whole host of players to get in on the goals.

"The way we are playing at the moment is very positive. But it's to do with our mentality and the way we've been approaching games, thinking, first and foremost, that we are hard to beat.

"Let's bed into the game for the first 20-25 minutes and not lose an early goal, and play the percentage football early doors, and then ease into the game a wee more and hope your quality comes through. I think we've done that."
