Nottingham Forest
1st season - Got promotion, and won FA cup.
Start of the season was horrible, as I completely rebuild entire squad, there was load of average players on high wages. After first 20 league matches I was on 15th position, and my best streak was draw, and two wins (first three games of the season), later team glued and we started winning only to lose title in the last match against wolves.
In FA cup I was a little lucky with draws, and won final with swansea in penalties.
2nd season - 15th, knocked out from euro cup in penalties of first knockout round by benfica. Rebuild squad again, bought a few regens, and some other youngsters, average age of my team was 21. So start was poor again, was even at the very bottom somewhere in the middle of the season. Ended up 15th, 11 points above relegation zone.
3rd season - 6th, knocked out from all competitions pretty fast. This time I made very few deals, most important ones being season-long loan of cleverley, and another courtesy of manu - 5,75m deal of Hernandez, he was exactly the players I was looking for, as I was in huge need of some typical poacher, and couldn't find anyone suitable. He ended up being top scorer in europe with 31 goals in 33 matches (many times he was coming off the bench, was scoring on average every 70mins).
4th season - 4th, knocked out from all competitions very soon, again. As for transfers, even tough I had 25m and 600k of wage budget left, I've gone only for free transfers (signed Caldirola, Tabanou, Junior Moraes, and Costil on pre-contract). Weirdly I had awful start of the season, I should thank there great draws in euro cup (got some slovenian team, turkish, and two russian). I know I could play there with some reserve squad, but I really wanted to progress there. After 13 matches, I was at 15th position, but then we really had a stormer, and were 1 point behind liverpool, and 3 points behind manu, while city won their 5th title in row.
I've to say that I intended, to play this save only for 1-3 seasons, just to get familiar with new FM, but I ended up really enjoying it, and I'm certainly not going to abandon this save anytime soon. The only weird thing is that my fan base isn't growing at all (around 100-200 more seasonal tickets each season), and I found it especially disappointing, as I wanted to build a new stadium, and as for now I rarely have a sell out for current one. In FM12 saves fan base seemed to grow a lot faster than that.
