You can't. You have to buy them from scouts. However, you can also choose to sign 5-star players who are 1 quality point away from the next star (such as 74, 79). So when you sign these players, you just have to train them little in order for them to become 6 stars. However, do note that a lot of managers know this, so expect some fierce competition from other managers. You can also sign players from the negotiations list, by negotiating with the managers on a certain player. Other than these methods, you can't get 6 star players directly, if you don't want to scout them. Regarding your second question, it is quite hard. You cannot definitely get him from auction. So, the only way is to buy scouts and train them till they reach the next level (which in this case you do not want). As for me, in my Top Eleven Career, I had only bought 1 scout (a striker) and he has not disappointed me as of yet. He always train 5 quality points in a single season (which means he is always 5 star). And he scores a handful number of goals which made me achieve a treble last season. This is his 4th season at my club, and I do not wish him to leave as he proved his worth, and I don't regret the amount of tokens I spent on him. Hopefully, he stays in my club for at least 2-3 more seasons (he was 20 when I bought him). So there you go....I hope I have answered your questions & good luck with your journey in top eleven!
