For a brief few hours on Sunday, they even topped the table after victory at Verona, their fifth win of an unbeaten start that feels like the next step for De Zerbi's entertaining team.
The 41-year-old coach might not have been the architect of Caputo's unusual movements but since taking over in 2018 he has controlled just about everything else at Sassuolo, this tiny club that has spent more time in Italy's fifth tier than its first over the past four decades.
De Zerbi himself is something of a cult figure in coaching circles. On the face of it, his is an unremarkable record. After going close to promotion with Foggia, there was a short and unsuccessful stay at Palermo before a doomed attempt to save Benevento from the drop.
It might not sound like much but the devil is in the detail.
"De Zerbi is one of the most innovative coaches in football," insists Melidona. "And his Sassuolo team are one of the most important teams in Italy right now."
It is not just the results, although many of those have been spectacular. It is not even the fact that they have been achieved on a fraction of the budget of Sassuolo's rivals.
It is the way that they are doing it.
"De Zerbi might change the players who start the construction depending on the opponent but he never changes the principles," says Melidona. "The team's idea remains constant. The fundamental principle of De Zerbi's football is that he wants his team dominate the game by constructing the game from the back and by keeping the ball on the ground."
Even Pep Guardiola has praised Sassuolo for their expansive approach and that is appropriate given that it was on a visit to watch his Bayern Munich team in 2013 that De Zerbi's vision for the game was crystallised. He wanted his teams to play football like that.
Now, it is others visiting Sassuolo to learn from him.
A recent cohort of the UEFA Pro Master course went to see De Zerbi to understand his methods. "I have no secrets," he told them. His game is right there for everyone to see on the pitch every single weekend.
Sassuolo are the top scorers in Italy and, with a nod to Gian Piero Gasperini's Atalanta, they are playing the most attractive football too. No team has played as many passes this season, with 22-year-old midfielder Manuel Locatelli, a precocious talent, at the top of the list.
Tactics of Sassuolo explained
"Sassuolo not only plays the most passes but they play the fewest long balls," says Melidona. "It is a very ambitious style of play and the influence of Guardiola is clear. De Zerbi always plays with five or six men attacking. The left-back or right-back joins in. The idea is always to fill the half of the opponent with as many players as possible.
"Sometimes, he starts with three players and the goalkeeper. Other times, he starts with four players and the goalkeeper. But the principle is always to dominate the game starting from a low construction, to retain possession and to control with and without the ball.
"He uses the whole width of the field. Right now, his scheme is to play with four defenders, two midfielders, three players between the midfield and the striker, and one striker.
"It is very important for him to play with his two outside players in the attack as inverted wingers, with the left footer on the right and the right footer on the left. That is because he wants width but he needs the wide attackers to move inside the box in the final third."
An example of this came on Sunday when, in top scorer Caputo's absence through injury, Sassuolo's goals in a 2-0 win were provided by Domenico Berardi, their left-footed right-winger, and Jeremie Boga, the former Chelsea youngster, who cuts inside from the left.
Much like Guardiola's teams, Sassuolo's expansive approach can leave them susceptible to the counter-attack and that has been reflected in some crazy scorelines. Just last month they followed up a 4-3 away win against Bologna with a 3-3 draw at home to Torino.
On Saturday, Sassuolo face Antonio Conte's Inter, against whom they drew 3-3 last time out in June having lost this corresponding fixture 4-3 last season. Entertainment is guaranteed.
"The problem is that using so many players in attacks does leave a lot of space in behind when possession of the ball is lost," says Melidona. "This is why even when Sassuolo win, they sometimes concede goals. Maybe it is a risk but it is a principle of De Zerbi's football.
"Sassuolo always try to score one more than the opponent. Sometimes the problem is that when he plays against a big team, if they do not take their chances they cannot come back."
Sassuolo in the Champions League?
In their favour is the fact that Sassuolo are improving. Young talent such as Locatelli and Boga have yet to hit their peak. Even Berardi and the veteran Caputo continue to add to their game under De Zerbi. It is a product of the style. With lots of touches of the ball and opportunities to express themselves, players are unlocking their talent like never before.
The packed schedule could also work out well.
"I think they have an important advantage," argues Melidona. "The season is short and Sassuolo only has to play in Serie A. Almost all of the other teams are playing in Europe. This could be an important advantage because they are playing only once a week.
"Maybe there could be a surprise and, to be honest, I hope that Sassuolo can qualify for the Champions League. It would be an important moment for Italian football."
Perhaps De Zerbi will move on eventually, although Melidona does not expect to see it happen while Champions League football is still a possibility. And, in Caputo, he is convinced that Sassuolo have a senior player within the ranks who can carry them to glory.
"At Entella, each Sunday he would score but each Monday he would be the first to arrive at the training ground. He would be the one who dragged the team through, the one who pulled the group through training. The mental strength that he possessed was incredible."
Melidona claims that for his old Entella team, "being in Serie B was like being in the Champions League" given the size of the club. Now, under the guidance of De Zerbi and his sensational Sassuolo, Ciccio Caputo is dreaming of being in the Champions League for real.
