The Stamford Bridge boss spent two years out of the game after he was sacked by Inter Milan, and it seems the former-Liverpool boss kept himself busy by lending his expertise to the creation of a coaching tool for budding managers.
While some coaches prefer the magnetic board, or maybe even the old-fashioned chalk board, Benitez has taken his coaching methods into the 21st century with the Globall Coach app.
The iPad version comes in three price categories - the 'Lite' for school or Sunday League gaffers at £4.99, 'Premier' for those more serious sideline generals at £50, and an 'Elite' version for UEFA-licensed coaches priced at £300.
The report compares it to an old Football manager game, allowing managers to juggle their squads, and run through on-pitch situations and formations at the drop of a hat.
Elaborate training ground set-pieces can be formulated and perfected, in virtual reality if not in practice, and in-depth post-match analysis can help you work out where it all went wrong, or right, during the 90 minutes.
Benitez revealed he wished he had a device like this when was a young manager growing up in Spain, and the new Chelsea boss explained the thinking behind the app to technology website Pocket-Lint.
Benitez said: "A lot of people have iPads now. But I haven't seen anything like this program.
"A lot of them have a PC, which they can use to download video, etc. But to go to the pitch with this, this level of information and the way you can change everything, I haven't seen this.
"When I was a young coach, I had two VHS video players and I was using both to prepare my case for my players.
"I would spend maybe five hours in the morning to prepare clips. With this technology you can do things like that [snaps fingers]."
And the Chelsea boss explained how the app would make life easier for coaches who have to manage cosmopolitan squads, with a number of different languages.
"The other thing is that I have been at a lot of top sides and they have a lot of foreign players, something it's difficult to communicate," added Benitez.
"Liverpool had 14 nationalities. And, at other teams, I've seen a translator on the pitch explaining the exercises during the training sessions.
"With this you can show them the exercises yourself."
