I don't understand this talk about letting go and not letting go. People like Miretti, Zhegrova, Openda, Kostic, Koop, Gatti, Cabal, Perin also have a job here and they don't play for free but get paid millions for it. Let it be their cup if they agree to not give up and to fight as if it were the World Cup final, they have nothing better to do anyway. Add to that Holm, Boga, and the best of NextGen, and there won't be a better opportunity for them to integrate and show up.
And if Spalletti sees that someone is slacking off, send them to Serie C. If they're too weak for Atalanta's reserve team, they have no place at Juve either.
