Pep Guardiola's side made contact over Wharton as they search for a long-term successor to Rodri, who completed his move to Barcelona for around £65m earlier in the window.
According to David Ornstein of The Athletic, City were told in no uncertain terms that the 22-year-old is not for sale this summer, with Crystal Palace determined to keep hold of a player they signed from Blackburn Rovers for £22m in January 2024 and who has since become one of the first names on Pierre Sage's team sheet.
Wharton has made 96 appearances for Palace, scoring once and adding 12 assists, and has already been capped four times by England. Liverpool and Manchester United have also been credited with interest in the midfielder at various points, though Palace's stance has remained consistent throughout the window: he simply is not available.
Sarr's situation is more complicated. Galatasaray have submitted a formal offer for the Senegal international, according to Fabrizio Romano, as the Turkish champions look to strengthen their attack. The 28-year-old is said to be open to discussions over a move to Istanbul, though any deal ultimately rests with Palace, who regard him as central to their plans under Sage.
The winger scored 21 goals and provided one assist in 45 appearances last season as Palace enjoyed arguably their finest campaign in the club's history, one that yielded the club's first major European trophy with victory in the Conference League.
Interest in his signature has hardly been limited to Galatasaray, with Manchester United previously credited with checking on his availability too. Sarr, who joined from Marseille in the summer of 2024, is under contract at Selhurst Park until 2029.
Whether either deal gets over the line before the window closes remains to be seen, but Palace's message so far has been unambiguous: two of the players central to their rise are not for sale cheaply, if at all.
