In November of my 4th season already. Won the Champions league two years in a row, league 3 years in a row (went undefeated in my 3rd season too), only 1 fa cup and no league cup though. Always feck up in those because I do full rotations for it. Bought Dolberg at the start of my 3rd season and he was back up striker to Dybala, but he scored 30 goals playing as a rotation player so I ended up selling Dybala since he kept asking to leave for PSG or Real Madrid. Madrid got him for 130m right before the 4th season started, though Dybala won the ballon d'or and was class for me. Also sold Gelson Martins because he wanted more then just squad player football. Same with Lingard.
Instead of bringing in a bunch of new depth, I just promoted Tahith Chong and Angel Gomes to full squad players pretty much and they've been alright. Also bought Jadon Sancho from Dortmund to have those 3 as my backup front 3, but it's a bit weak since they're still very young. They do ok though. Have Herrera, Andreas Pereira and Seri as my back up midfield, then back up defence is Blind, Sarr, Tuanzebe and Fosu Mensah. Some youth regen as back up goalkeeper since he has 5 star potential.
Starting 11 is now:
De Gea
Valencia Bailly Lindelof Tierney
Soler
Asensio Pogba
Rashford Dolberg Martial
Pretty dominant with it, though I'll probably struggle more with the depth being weaker. Already on 2 losses in all comps compared to going undefeated in the league last season.
Side note - finally have a title challenge this season, Chelsea after 9 games has 1 draw and 8 wins. Was too easy to win the title the other years, 2nd place having 78, 73 and 76 points for the previous 3 years. Would basically have the title wrapped up in March.
