Juan Guillermo Cuadrado began pre-season training with Fiorentina and is set for a crucial meeting on Friday.
The Colombia international returned from his post-World Cup vacation and underwent medical tests today.
The Viola released video footage of him going through the battery of tests with medical staff before he began pre-season training.
It is reported Cuadrado will meet with patron Andrea Della Valle on Friday in a decisive meeting over his future.
Barcelona and Manchester United are those most actively interested in the winger and prepared to pay his minimum €45m (£36m) asking price.
Fiorentina have repeatedly stated they want to keep Cuadrado, but will listen to offers if he requests a transfer.
