For Juventus and Manchester United, this is beneficial to their own strategic strategies. On the one hand, Juventus has gradually established a system with Cristiano Ronaldo as the core since he joined in July last year. Now this transaction is in the interest of the system. Because when Lu Kaku joined Juventus, Lu Kaku could play center and Cristiano Ronaldo played left forward.
Moreover, Dibala's own strength is good, and the assist team has also achieved many good results. It is actually relatively fair for two players with equal strength to exchange. I believe that if Manchester United and Juventus can make such a big deal, at least from the long-term interests of their own teams, they will not suffer.
As far as Lu Kaku and Dibala are concerned, recently, because Lu Kaku publicly "tore" Manchester United and accused it of unfair treatment, the two sides have had some friction and unhappiness on the Internet. I believe this unhappiness is not only due to overnight, but also due to various interests and arrangements in the team on weekdays. However, we can all feel Lu Kaku's inner dissatisfaction and resentment to a greater or lesser extent, and expect Lu Kaku to cooperate more happily when he enters the new team.
For Dibala, leaving Juventus may not be his own voluntary choice, and there may even be some compulsion, but because the boss has approved it, he can only strive to maximize his own interests. There have been rumors that Dibala's sky-high offer was rejected, and I don't know if it is true or not. But actually Dibala's strength is really good. After joining the Argentine team, he participated in various major competitions many times. But because it overlaps with Messi's position, it is difficult to get more opportunities to shine. This powerful player, called Messi's successor, may have a more suitable position in another new team.
