MATT Jansen has set his sights on gunning down Portsmouth tomorrow after admitting that last week's wonder goal against Liverpool has given him a massive shot in the arm.

Jansen's stunning eighth minute strike was his first Premiership goal at Ewood since he bagged a brace in a 3-2 defeat against Arsenal in January last year.

Although it proved to be little more than a consolation on the day, it was another important landmark in Jansen's journey back from the brink and now the 25-year-old is looking forward to happier times ahead after finally ending his 20-month barren spell.

"It was very pleasing to score," said the Rovers striker.

"A goal at Ewood has been long overdue but, thankfully, I got one last week and hopefully the next one won't take quite as long.

"The more games I play, the more I can feel my confidence being boosted, and scoring goals like that is a huge bonus.

"So I'm sure I'll be saying before too long that I don't want to come off in games.

"At the moment, I'm saying to myself 'the gaffer is treating me well by easing me back into it slowly.'

"But before too long, I'm sure I'll be in a position where I'm saying 'No, I don't want to come off' because I'll be feeling so confident and arrogant that I won't want to."

This was always going to be a huge season for Jansen considering what has happened to him during the last 18 months.

Some critics questioned whether he would ever be able to perform effectively at the top level again after he suffered a serious head injury as a result of a motorbike accident last summer.

However, his response in the opening month of the new season has done much to silence the doubters.

He scored his first Premiership goal in 16 months at Bolton recently when he reacted sharply to sweep home a David Thompson cross.

Then he showed further evidence of his rejuvenation with an assist at Chelsea three weeks ago as Rovers emerged from Stamford Bridge with another hard-earned point.

But the clearest sign yet that he's on his way back was witnessed against Liverpool last weekend when he out-foxed England defender Jamie Carragher, cleverly juggling the ball from one foot to the other, before arrowing a precise finish beyond Jerzy Dudek.

"Two months ago, I would have snapped your hand off if you'd have offered me that," said Jansen.

"Now I've just got to keep going. I feel like I'm heading in the right direction so, hopefully, it won't be long before I'm back to where I was two days before the accident happened when I was on the verge of the England squad."
