Saha is a natural finisher, there is no doubting that. What he can't do is play as a lone striker, come deep, hold the ball up and lay it off, its not is game. The best performance I have seen of a striker (at goodison in a long time) was the Blackpool game, regardless of the goals he scored his overall performance was excellent and he ran their defenders everywhere.
If Saha plays week in week out at Spurs, I honestly wouldn't be suprised if he got into double figures by the end of the season; the free flowing football Spurs play is totally different from our slow, stagnent build up and I believe Saha will benefit, he may not be running the line, or chasing into the flanks, but he'll be at the end of many attack
