Watford will welcome back Heidar Helguson for tomorrow's trip to promotion-chasing West Bromwich Albion.

The striker, who scored 64 goals for the Hornets in his first five-and-a-half year spell in Hertfordshire, marked his return to the club in September by coming off the bench and scoring two goals in a dramatic 36-minute cameo against Leicester City.

The Iceland international went off with a calf strain though, and has not featured in the six games since.

But yesterday Malky Mackay confirmed the on-loan QPR striker would be available, although he claimed the decision on whether the 32-year-old would start will not be made until today.

"We have got Heidar Helguson back involved and available this weekend," Mackay said. "He has trained very well this week and it is a big boost to have him back.

He added: "I am going to look at it tomorrow. We have been building up all week and planning but I will look at it again tomorrow before deciding what I am going to do with him."

Ross Jenkins will miss out though, after the 18-year-old's 50th career start ended prematurely last week due to a back injury.

Richard Lee is still a couple of weeks away from full fitness after jarring his knee but apart from that, Mackay has no other injury concerns.

On Wednesday, a Watford XI took on a young side from Premier League-leaders Chelsea and won 2-0 thanks to goals from Liam Henderson.

Jure Travner, Scott Severin, Will Hoskins and Mat Sadler all played the full 90 minutes.

It has been an excellent couple of weeks for Watford and Mackay believes taking seven points from a possible nine in their last three games has proved his side "can be competitive in every game".

He said: "I think to go to Middlesbrough and Ipswich and then have a real good home win on Friday night, it was a good week's work as far as the boys are concerned and it gives them confidence that they can be competitive in every game we are in."

The 4-1 thumping of Sheffield Wednesday saw his side receive rave reviews from the media but the Hornets boss insists no one has let it go to their heads.

"I have not had anyone swanning around here thinking they have made it and done it," Mackay said.

"I am too long in the tooth to let that happen but I have not seen any sign of that. There is no reason why that would happen as I have a good group here."

The Hornets have not beaten West Brom in the league since February 1995 – a run of 12 games.

And Mackay knows it is going to be tough to end that record against Roberto Di Matteo's side.

He said: "Roberto was the manager when we played MK Dons a few years ago and he likes to play expansive and open football and his teams are always comfortable on the ball.

"West Brom have still got a lot of the players from their Premiership year so they are at the top of the division and flying high. It will be a tough place to go, the Hawthorns, it always is, no matter who the manager is."
