Visa-free and loan players have always been the most "money-saving" transfer operations, but free is not necessarily a good thing, and there have been many visa-free and loan transfers this summer. In addition to the high salaries of the players in this class, the team also pays for their performance.
Georginio Wijnaldum, 31, chose not to renew his contract with Liverpool this summer to move to Paris Saint-Germain in Ligue 1 on a free throw, earning a huge salary. However, at PSG, the team's midfield is really overcrowded, in addition to him there are five international-level strength midfielders, such as Italian midfield core Marco Verratti, former Everton midfielder Idrisa Guy, Portugal international Danilo Pereira, former Manchester United midfielder André Herrera and Argentina international Leandro Paredes, all five of whom are no worse than Wijnaldum. In this season, Wijnaldum can only be a rotating member; his competitive status is not as good as when he was in the Reds. Rumor has it that the Dutchman wants to leave the team in the winter window and end his nightmare in Paris.
Argentine super scorer Sergio Agüero may have been forced to retire because of heart problems, but before the heart problem, the manchester City's all-time top scorer did not perform well, and because of the injury, he was delayed from playing. After spending several months in Barcelona, Aguero only scored one goal in La Liga four times, and he seemed to have been "deceived" by Barcelona when he failed to play with Messi.
Chelsea have been understaffed in midfield, so they borrowed Atletico Madrid's Saúl Ñíguez in the summer, hoping that he would be able to play a rotation role even if he did not have the opportunity to become the team's fourth midfielder. Unexpectedly, the former Spain international could not even play at the level of one-third of his heyday, in addition to the lack of confrontation, his basic passing, decision-making, and ball-holding advancement were also quite poor. Thomas Tuchel gave him a chance, but he wasted them all; he contributed to the "hell level" performances in the Premier League games against Villa and Watford; in the Champions League match, Saul Neggs was moved to the left wing, and his performance was equally poor, and it seems that his days at the Blues have come to an end.
Another PSG player, this summer, Paris Saint-Germain introduced a group of high-paid free signings with mixed reviews, and Sergio Ramos was the worst in the middle. The Real Madrid captain has been injured since joining the team and has only played for the team once so far, and after playing against Saint-Etienne, Ramos continued to recuperate from injury. It is rumored that PSG feels cheated and hopes to terminate the contract with this high-paid player; but Ramos and the team have signed a two-year contract, and it is really not easy for PSG to "send a guest".
