Saha key to United's plans

Tonight's Champions League clash with Sporting Lisbon marks the first time Sir Alex Ferguson has had Wayne Rooney, Cristiano Ronaldo and Carlos Tevez all available for selection.

But while Reds fans will be licking their lips in anticipation of what this talented trio could deliver, the United boss insists the secret to success in this season's European campaign lies elsewhere.

"I think if we can get Louis Saha to stay fit then that will be a big, big bonus," the manager told English press in Lisbon.

"The other players are all tremendous footballers, but Louis is different and adds different ingredients. The power and strength of Saha is very important in Europe and it's key he remains fit."

It was Saha who grabbed United's winner in Portugal last season, with a 60th-minute strike to sink Benfica in the group stage. He also scored in the corresponding home fixture and twice against Celtic at Old Trafford.

Sir Alex revealed the Frenchman, who has just 72 minutes of league action under his belt this season after suffering a knee injury towards the end of last season, would certainly play a part in tonight's match. Like his other strikers, however, he's uncertain just how big the role will be.

"We're still in the process of picking our moments with Louis – when he does and doesn't play," he said.

"Rooney will be involved against Sporting, and Tevez too. I have good attacking options and I'll be using them all throughout the game.

"At the moment we're showing a good team spirit and a good work ethic. Our defenders have been wonderful in the last three games and that immediately gives us a good chance of winning matches. And we have the players to do that."
