PA:
It has already been rumoured Ferguson might be about to make a big-money move for Atletico Madrid's Spanish international Torres.
However, after initially trying to joke his way out of talk over January transfer targets, he eventually returned the kind of non-answer which suggested he may be looking to bring in reinforcements.
"How many times have I bought players in January?" he smiled, before being reminded that Saha himself was a mid-season purchase, while Patrice Evra and Nemanja Vidic arrived for a combined fee of £12million in the first month this year.
"Okay. There were a few. We will have to see what happens."
However, given the outstanding contribution Saha has already made this season, it is difficult to see how anyone could oust the Frenchman from Ferguson's preferred starting line-up, no matter how much they cost.
The key for United now is to keep the 28-year-old out of the treatment room.
"As we keep saying about Louis, we have to keep him fit," said Ferguson. That is the key for him.
"He had a terrible spell when he first came here. He got injuries playing for France and one with us last summer in Japan that kept him out for four months.
"But when he came back he immediately started to score goals, first in the League Cup, then he had a good run in the league.
"His ratio of goals per game is healthy and he is a very important player for us."
