The 4 clubs that can transfer Cristiano Ronaldo before the end of the transfer window

Cristiano Ronaldo has been trying to leave Manchester United all summer. The five-time Ballon d’Or winner started on the bench as the Red Devils beat old rivals Liverpool 2-1 at Old Trafford.
The Dutch coach has a system he wants to implement at United and Ronaldo is not suited to it.
The 37-year-old is said to want to play Champions League football and his agent Jorge Mendes has offered him to a number of big clubs this summer.
However, most of these clubs have turned down the chance to sign the veteran striker.
#4 Sporting CP
Cristiano Ronaldo could secure a return to his boyhood club Sporting CP.
#3 Chelsea
Chelsea were among the first clubs to be linked with Ronaldo this summer. According to English journalist Simon Phillips, new Chelsea owner Todd Boehly is a big fan of the Portuguese legend and really wants to sign him.
#2 AC Milan
If reports are to be believed, super agent Jorge Mendes is running around Europe knocking on the doors of the European giants hoping to get his client playing Champions League football again.
#1 Napoli
Will Ronaldo be able to add a Diego Maradona-like chapter to his career in the closing stages? It may be too early to rule this possibility out.
