“The way in which Fabio assaults jogs my memory of Pantani,” Martinelli stated in an interview with The Related Press. “Yesterday’s assault was identical to one in every of Pantani’s strikes.

“In addition to making the opposite guys harm, he additionally created a spot. And he is bought the braveness to strive,” added Martinelli, who has coached Pantani, Stefano Garzelli, Gilberto Simoni, Damiano Cungeo, Vincenzo Nibali and Aru to a complete of 9 Grand Tour victories.

The Stage 5 victory Wednesday on the Planches des Belles Filles ski station in japanese France’s Vosges mountains was the place Nibali arrange his 2014 Tour title, changing into the one rider to interrupt Froome’s hegemony over biking’s greatest occasion amid the British rider’s wins in 2013, 2015 and 2016.

Whereas Aru is just not as full as Nibali, he appears to have an additional gear within the mountains.

“These days, numerous climbers assault solely once they’re positive they’ll attain the end, with 500 meters or a kilometer to go,” Martinelli stated. “Aru attacked with 2.5 kilometers remaining on a 5-kilometer climb. On a 10-kilometer climb he might be able to attacking with 5K to go.”

No matter he is able to, one factor is for positive: Aru — his title is pronounced with the accent on the primary A — has hastily turn into a severe risk to Froome, the yellow jersey holder.

With extra climbing on the route this weekend, particularly Sunday’s stage to Chambery within the Alps, which incorporates three beyond-category ascents, Aru might be seeking to enhance on his third-place place within the standings and erase his 14-second deficit to Froome.

Pantani had the same construct however his profession was derailed by doping instances and he died of cocaine poisoning in 2004.

So is Aru clear?

“He exhibits it day-after-day. Biking is clear now,” Martinelli stated. “I’ve bought a son who’s a professional and I do know that 99.9 p.c of the riders racing now are clear.”

The large query for Aru is whether or not he has the stamina to maintain up with Froome and different contenders like Richie Porte in phases with a number of climbs.

Froome stated he let Aru go as a result of he nonetheless had two Staff Sky members defending him and knew Aru was far again within the standings.

“In hindsight, I might have accomplished issues in another way however actually going ahead I am not going to observe him experience away,” Froome stated.

“He needed to depart his household when he was 16 and transfer north to coach,” Martinelli stated. “His is a really Italian story in that he needed to to migrate to seek out success. It did not all come straightforward for him.”

Aru has additionally had two podium finishes within the Giro and at 27 stays comparatively younger for a Grand Tour contender. Nonetheless with no contract for subsequent season, he is a prized commodity.

“Often when (Astana crew supervisor Alexandre) Vinokourov needs to maintain one thing he does,” Martinelli stated. “I am assured he’ll stay right here.”
