Form and player morale play a massive part in FM2006. Make sure you're patched up too, fixes a few niggly bugs. Don't drop players if they're playing well, even if a supposedly better player comes back from injury or suspension or whatever. Give your players credit where it's due - i often find saying "well done" to all the team and "fantastic" to one member of the team that has played an 8 or higher works really well.
I've managed to get Ipswich to be Premiership champions and Champions league champions in <5 years, which I was really please with.
