Chelsea Close in on Mamadou Sarr Amid Loan Hurdles and Squad Shake-Up

Chelsea has struck a deal with Strasbourg's Mamadou Sarr for a £16.9m January transfer, but existing loan agreements pose obstacles. The club must recall a player to comply with FIFA rules, with Andrey Santos the likely candidate. This move fits Chelsea's youth strategy and could affect Trevoh Chalobah's role.
