Paris Saint-Germain were supposed to right many wrongs from previous years with the appointment of the proven duo consisting of head coach Christophe Galtier and sporting director Luis Campos. But the project failed.They brought in many players but failed to balance out their squad. It led to them having to rely on kids like Warren Zaire-Emery and El Chadaille Bitshiabu in the most crucial game of the season, the UCL knockout second leg at Bayern. Meanwhile, Ligue 1-winning midfielder Renato Sanches was nowhere to be seen. The former Lille star joined PSG for around $15 million at the start of the season but will likely leave soon.The Portuguese midfielder has failed to establish himself in the Parisian team, and his physical fragility poses serious problems. Since arriving in Paris, Sanches has already spent 85 days in the infirmary and missed 16 competitive matches due to various injuries. Despite the hopes placed in him, he failed to live up to expectations. Renato Sanches saiu lesionado com apenas 9 minutos de jogo.É a quinta lesão do português esta época 💔 pic.twitter.com/umIp9bdDZb— B24 (@B24PT) April 8, 2023 Overall, the former Bayern Munich man has 18 appearances this season, and his litany of injuries have seen him grow frustrated. Although sporting advisor Luís Campos and manager Christophe Galtier know him well from their Lille days, have ostensibly not been able to unlock his potential as of yet. Sanches has privately complained about his lack of playing time, having yet to complete a full match for PSG.As was the case in his Lille days, the Euro 2016 has been plagued by injuries – this campaign alone has seen him suffer from adductor, bruises and hamstring injuries. The latter issue had kept him out for a month before his first start in two months against Lyon ten days ago, which ended after just ten minutes after yet another injury.Campos could be tempted to part with Sanches to free up payroll to make room for new reinforcements. However, the former Lille player has a contract until June 2027 with a monthly salary of $550,000 gross, which complicates matters. The Portuguese could be reluctant to sit on such a contract in the event of departure from PSG.##NAJAVA_MECA_7171452##One thing is certain: the capital club leaders will have to decide quickly on the future of Renato Sanches. If the player is still appreciated for his footballing qualities, his physical fragility could get the better of his career in Paris. And if the PSG decides to separate from him, it will then be necessary to find a buyer ready to assume his salary and his recurring injuries.The PSG medical staff have opted for surgery to minimise the risk of a recurrence. The operation will be performed in Finland today and will make him unavailable until at the end of the season.The former Leipzig player had been one of the rare satisfactions of the summer transfer window and had been able to replace Achraf Hakimi effectively. It won’t be an enjoyable run-in of the season for Galthier.
