The 20-year-old came through the youth system at Blackburn Rovers, progressing to first-team level in 2022, and he represented their senior outfit on 51 occasions before moving to Palace in January.
Wharton was in excellent form for the Eagles in the second half of the 2023-24 campaign, providing three assists in 16 appearances, and he earned a spot in the England squad for Euro 2024.
The midfielder is yet to take to the field at the European Championship, but he could have a role to play in the final of the competition against Spain on Sunday night.
Wharton's impressive performances for Palace have led to a host of speculation surrounding his future, with Man City said to be keen to secure his signature this summer.
Bayern Munich, Real Madrid have also been linked with Wharton
Bayern Munich and Real Madrid have also been credited with an interest in the midfielder, with Palace seemingly facing a huge task when it comes to keeping hold of him.
However, according to The Sun, Wharton is set to hand Palace a major boost, with the youngster happy to continue his development under Oliver Glasner at Selhurst Park.
Wharton penned a five-year deal with Palace upon his arrival, so the Eagles are in a strong position when it comes to keeping hold of him during the summer market.
Palace have already sold Michael Olise to Bayern during the current window, while Eberechi Eze continues to be linked with a move away from the club, with Liverpool, Manchester United and Tottenham Hotspur all thought to be keen on his signature.
What is the latest transfer news at Man City?
Ederson continues to be heavily linked with a move away from Man City, with the club said to have received a £25m offer from a Saudi Arabian team for his signature.
However, the Citizens are allegedly preparing to offer their number one goalkeeper a new contract in the hope of keeping him at the Etihad Stadium.
Julian Alvarez is also being linked with a departure, with the Argentina international thought to be looking for a starting role next term, while Joao Cancelo is expected to leave.
Al-Ahli and Al Ettifaq are thought to be willing to pay around £21m for the right-back, while a return to Barcelona cannot be ruled out despite the Catalan outfit's financial issues.
In terms of incomings, Man City are believed to be ready to battle Man United for the signature of Paris Saint-Germain midfielder Manuel Ugarte.
