Manchester United may have splashed out £150m on Marcos Rojo, Luke Shaw, Daley Blind, Ander Herrera, Angel Di Maria and Radamel Falcao this summer, but that hasn't prevented transfer rumours linking new manager Louis van Gaal with more big money swoops in January and even next summer.
Mats Hummels, Kevin Strootman, Arturo Vidal and Marco Reus continue to be linked with blockbuster moves to Old Trafford, but there's one name that beats them all - Cristiano Ronaldo.
The Portuguese international first joined Manchester United in 2003, and is still considered an Old Trafford legend. In six seasons with United, Ronaldo hit 118 goals in 292 games, before completing a then-world record move to Real Madrid for £85m.
Since moving to Spain, Ronaldo's goalscoring feats have improved exponentially, smashing a mind-boggling 269 goals in only 257 games for Real - well over one goal every game. Approaching his 30th birthday, it seems that Ronaldo is on the verge of another Ballon d'Or title, but questions still remain over his long-term future in the Spanish capital.
Recent speculation has suggested that United want to complete a blockbuster deal to bring Ronaldo back to Old Trafford, and with rumours gathering pace, his Real Madrid team mate Gareth Bale has made it clear that he doesn't want his fellow wing wizard to leave.
"Definitely not. He's shown what a world-class player he is year after year scoring the goals," said Bale. "Obviously he's a player we wouldn't want to see leave. Of course, I want to see him stay at Real Madrid."
