His team has financial problem.
Even if he use tokens to buy scout players instead of using cash to buy player through auctions, he still needs to pay wages and other expenses. I don't think this can solve his problem.
In case you will elaborate and tell us that you train players to higher value and then sell for profit. It's only possible in low levels. FCBarca is at least level 14. If his team is over level 20. There is almost no increase in player value even if players extremely hardly train.
