If you have two players up front, the best two players to have are Henrik Larsson and Andriy Schevchenko. They are guaranteed to score every game, as long as you have a brilliant play maker like Zinedine Zidane.
As soon as you start a season, buy Cherno Samba who is 15 and plays for Millwall. If you play about 10 seasons he will become one of the best strikers. Also, Arjen Robben who is 17 from Groningen and Rafael Van Der Vaart who is 18 from Ajax are excellent prospects for the future.
