United are chasing an unprecedented fourth successive league title, and are only a point behind leaders Chelsea now after drawing 1-1 at Aston Villa.
Saha, who scored twice at Goodison, will hope he is in the same rich vein when United travel to Merseyside next week.
Delight: Saha celebrates at Goodison Park on Wednesday
Saha, who left United on a free transfer 18 months ago, said: 'I'd love to say Everton could win it, but that's not going to happen.
'Chelsea are very strong, but I think United are better - and I would be delighted if they won it. I'd prefer that.
'I still keep in touch with a lot of them from United, especially Patrice Evra. And Wayne Rooney and Owen Hargreaves are on the phone a lot.
'They've got a really good bunch of guys. I know I will be getting a lot of calls now, and it is a big boost for United. But the main thing has to be Everton, and taking us as high up the table as possible.'
Chelsea skipper John Terry was at fault for both Everton goals, and has now flown out to Dubai to try and patch up his marriage.
Heads up: Saha scores Everton's equaliser against Chelsea
He missed Sylvain Distin's long ball 15 minutes from time, and Saha swooped to score the winner, but the striker told the Sun he believes Everton should be making the news, not the errant Chelsea defender.
Saha, who signed a new two year deal with Everton last week, added: 'I know what people are saying but they have got to realise what a great ball it was. You make the runs and know they're going to pick you out, so I wasn't surprised when it came to me.
'As well as Sylvain, we've got Leighton Baines, John Heitinga and Phil Neville who can all hit passes like that.
'We should get some praise for showing great character to come back from losing to Liverpool.
'It was important to bounce back against top-class opponents.'
