Fabregas was only able to fill the head coach role for seven games as he did not have the required coaching licence.
Como therefore appointed former Wales assistant manager Osian Roberts to lead the team until the end of the season, with Fabregas staying on as his number two.
Like Arsenal’s Mikel Arteta and former Crystal Palace boss Patrick Vieira, Henry studied for his coaching badges in Wales under the guidance of Roberts, a former technical director at the Football Association of Wales.
Fabregas says Roberts’ contribution at Como has been “fantastic”.
“He’s been a mentor for me, challenging me, seeing how I would react in different situations,” the 37-year-old Fabregas said.
“When we were looking to bring someone in, Thierry recommended him. He told me that he was the right guy for us.
“I spoke to Mikel, and I spoke to Patrick because they worked together for two years at Crystal Palace. Everyone was very complimentary about him.”
Fabregas is due to complete his Pro Licence qualifications this summer, which would allow him to become Como’s full-time boss.
Roberts is expected to ‘move upstairs’ and focus exclusively on a head of development role, though Fabregas was not willing to give too much away amid Como’s promotion celebrations.
“There’s an announcement coming soon and you’ll have to wait for that,” he said.
“I’m very happy here. My intention is to be here. In a couple of weeks everything will be clear.”
Fabregas is aware of the “big challenge” ahead as he looks to keep Como in Serie A if, as expected, he becomes permanent boss.
“It’s going to be difficult because obviously we’ll be competing on the highest level, but we have a clear idea of what we want to do,” he said.
“I was the same I was as a player now that I’m a coach. We’ve had a successful season, but now it’s done. We have to move on to the next one.”
