Oh yes one more thing, now Juventus has also installed a clause for Douglas Luiz of € 25M price tag. And Man United is linked with:
Maybe Juventus were hoping that they could take these players and turn them into higher level players at their club. But if they were unstable players from the start, then they basically stayed the same. Now Juventus want to sell Vlahovic and Luis, but since they failed to prove themselves properly at Juventus, it is clear that it is difficult for them to get the price they want for them. And with Vlahovic, they have already been trying to sell him for the second transfer window in a row, so I think in this case it would be better to lower the price and replace him.
It's undeniable that Douglas Luiz was one of Juventus' failed signings last season. He didn't make a significant impact after signing for a transfer fee. That's why they let him go, for a high fee, but with practically no contribution. After checking here, it's clear why Juve was so eager to let him go.
