Loong and Rachel have both relatively old players in team's core. Rachel's defence looks too thin, but they have chances to survive here. For stable success all they need time to build up facilities that allow to buy younger line-up. When I arrived to League 1 quicker as I expected, my key to surviving were right special attributes, which gave me some 6th place finishes with weakest star value in league. Actually, then we had "big 4" far ahead of others and other teams quite close to each other, who mostly didn't train specialities on their TC. Some of them sneaked out my "secret" and started to close with top 4. Even my team has couple of 4th places and one cup.
Currently my team has some silent period with more homegrown players and target of collecting money for last stadium level. After that I'll have more free hands and money for upgrades and new players. It may take almost year.
