Chris Froome should put his efforts into winning the Giro d'Italia to cement his cycling legacy, according to Davide Cassani.
Briton Froome earned a dominant victory at last year's Tour de France to win cycling's most prestigious event for the second time in his career.
The 30-year-old is once more focusing his efforts on winning the yellow jersey in 2016, opting to forego the Giro for the sixth year running - his last outing ending in disqualification in 2010.
But Cassani, a former road cyclist who is now manager of Italy's national cycling team, believes that Froome would etch himself among the greats by going for Giro glory.
"I think that a rider like Chris Froome should prove himself in a race like the Giro sooner rather than later," Cassani, a two-time stage winner at the Giro, told Omnisport.
"Cyclists go down in history if they win different races, not only two or three Tour de France. [Felice] Gimondi and [Vincenzo] Nibali won all the three grand tours.
"I think it would be great if Froome, after having won everything he won, could show up at the Giro to win it, as he came in the past but he was not the Froome as we know him today."
Cassani's view is shared by two-time Giro winner Ivan Basso, who retired last year following a battle with testicular cancer, but the Italian sympathised with Froome's decision.
"We have to respect his plan. To race the Giro and Tour is very complicated," Basso told Omnisport. "I don't dare judge the technical choices of a great champion like Froome.
"On the other hand, since the calendar has the Giro before the Tour you have to make a choice and you dismiss the Giro.
"Still, I am sure Froome will doubtlessly come to try and win the Giro one day."
