Leeds manager David O'Leary is desperate for Mark Viduka and Alan Smith to recapture their goalscoring touch tonight as he pins his hopes of further Champions League glory on a shot-shy strike force.

O'Leary is without Robbie Keane for the visit of Anderlecht because the Republic of Ireland forward is ineligible to face the Belgian champions at Elland Road.

Since his arrival from Inter Milan just two months ago, Keane has helped turned round what seemed set to be a season to forget for O'Leary and has given his fellow Irishman renewed hope of success.

The £1m Leeds paid Inter for a loan deal until the end of the season has proven to be money well spent, ensuring there will be no qualms come the summer when it comes to spending a further £12m on securing a permanent move for the 20-year-old.

Keane's five goals in five games in January made him the Carling player-of-the-month.

But having played for Inter in the qualifying rounds, he is consigned to a watching brief.

Smith has scored just one goal in the last four months, albeit one of the most important of United's season because it was enough to beat Lazio in Rome in the last Champions League game before the mid-winter break.

Viduka has managed just one in two months, his dip in form coinciding ironically with the arrival of Keane after the Australian had found the net 13 times in his previous 18 matches.

With a place in the quarter-finals on the line depending on the results of the back-to-back matches with Anderlecht, O'Leary knows he needs Viduka and Smith to leave him nursing a future selection headache.

''I want Mark to start scoring, and the sooner the better,'' said O'Leary.

''I also want Alan Smith to come in and say 'right, I've been on the bench and I'm going to score goals'. I want them to cause me a problem.

''I want them to come on, net a bag full and then get me thinking about Robbie Keane. That's what I want out of the two of them.

''Obviously Mark has been playing more regularly, and I wish I could put my finger on why he has stopped scoring although it's a problem most coaches in the world wish they could work out when a striker loses his form.

''What he has done is make goals for other people, although I know he wants to start scoring goals again. All I can say is he's been outstanding in the Champions League, and maybe tomorrow will be a spur for him.

''Strikers are in there to score goals, and I know they haven't had the best supply line. What would really help Alan and Mark is a fit-again Kewell.'
