The Fiorentina chief says the chance of the Colombian joining Barcelona, Manchester United or Bayern Munich this summer have passed and he will remain in Serie A.
Barcelona was leading the race for his signature for months but was reported to have been put off by his high price tag and instead chose to sign Douglas Pereira from Sao Paulo to fill the void on the right flank of Camp Nou's midfield.
Manchester United and Bayern Munich were also heavily rumored to be chasing the Colombian but, on the eve of Serie A's restart, the Viola chief has confirmed that Cuadrado will remain with Vincenzo Montella's squad this summer.

"I can guarantee that Cuadrado is certainly staying," Della Valle told reporters. "It's a huge gift for the city. I hope it's the strongest Fiorentina in my era in charge."
Montella also expressed his delight that the in-demand 26-year-old will not be ditching the club ahead of the season and looked ahead to Fiorentina's opening game of the Serie A season at Roma on Saturday.
"I am happy, very happy indeed," the coach added. "Cuadrado's an important player for Fiorentina.
"Tomorrow begins a whole new season of expectation. There are no assumptions but there is a belief that must be turned into positive results. Roma are among the favorites with Juventus and Inter, whom I think are looking strong. Serie A's a league which looks stronger."
