Thought I would add my bit to this thread, I've not read every page so forgive me if I repeat things.
I'm currently in my 4th season with Man United and I've experienced two sides to this coin. In my first season the only game I lost ALL season was the FA cup final to Chelsea, winning European cup & Carling cup at a canter going unbeaten for 59 games untill playing Chelseas in the final. I didn't change tactics or do press conferences just team talks & shouts. Btw I started off with Sunday league experience.
Second season I finished 3rd in the league losing 6games, won the FA cup & lost in the final of the Champions League.
Third season I done the treble, easily winning the league & regulary thrashing teams 4 & 5 nil.
Obviously things are not right an hopefully the next update will balance things out a bit.
