As Real Madrid star striker Cristiano Ronaldo watched, the World No 4 Nadal went past Italian Bolelli to set up a quarter-final clash against 10th seed Grigor Dimitrov.
Local hero Rafael Nadal raced into the last eight of the Madrid Open when he brushed aside unseeded Italian Simone Bolelli 6-2, 6-2 on Thursday to set up a quarter-final clash against Bulgarian 10th seed Grigor Dimitrov.
Chasing a third straight title at the clay Masters event in the Spanish capital, and a fifth overall, third seed Nadal needed little more than an hour to see off an outclassed Bolelli, saving both break points he faced on his serve.
The Majorcan has a good chance of claiming another Madrid crown as World No 1 Novak Djokovic pulled out to rest and Roger Federer, who took over from the Serb as the top seed, fell to Australian Nick Kyrgios in the second round on Wednesday.
After struggles with injury and illness, Nadal is attempting to rediscover his best form on his favoured surface before he makes a bid for a record-extending 10th French Open singles title in Paris starting at the end of the month.
He won a 46th career clay title in Buenos Aires in February and is just three shy of the record of 49 held by Guillermo Vilas, but fell short at subsequent clay tournaments in Monte Carlo and Barcelona, two events he has won multiple times.
Dimitrov earlier edged eighth-seeded Swiss Stanislas Wawrinka, who Nadal beat in the 2013 Madrid final, 7-6(5) 3-6 6-3 and the Spaniard said he was expecting a tough contest even though he has beaten the Bulgarian in all five of their previous meetings, including twice on clay.
"Yeah, everything worries me about Dimitrov," Nadal told a news conference.
"He's a very good player. He serves well, very good forehand. Backhand, too. Slice also.
"He moves very well and has good footwork. He is a very complicated player. All round. Only way to beat him is to play at really high level.
"Let's see what happens. I hope I'm going to be ready for the match and I'm going to have fun."
Czech Tomas Berdych, the sixth seed, also claimed a berth in the last eight when he cruised past 12th-seeded Frenchman Jo-Wilfried Tsonga 7-5, 6-2.
Berdych, who lost to Federer in the 2012 final, will play 16th seed John Isner on Friday for a place in the last four.
American Isner brought Kyrgios back down to earth with a hard-fought 6-3, 6-7(7), 6-4 success.
On the other side of the draw, second seed Andy Murray thrashed Spanish wildcard Marcel Granollers 6-2, 6-0 and will play Milos Raonic of Canada in the quarter-finals.
Raonic, seeded five, battered down 11 aces as he cruised past unseeded Argentine Leonardo Mayer 6-4, 6-3.
David Ferrer, the seventh seed, ousted Spanish compatriot Fernando Verdasco in an entertaining encounter 5-7, 6-3, 6-4 and will play last year's beaten finalist Kei Nishikori.
The fourth-seeded Japanese, who had to retire from the 2014 showpiece against Nadal due to injury, beat another Spaniard, 14th seed Roberto Bautista, 6-3, 6-3.
