The consistent full-back has clearly gained an admirer in the German boss.
The 27-year-old's renewal was met warmly by supporters and pundits alike, while his manager Uwe Rosler has now spoken out on the deal which will ensure their working relationship continues well into the future.
As declared in an interview aired on LUTV ahead of his team's game at Middlesbrough this weekend, Rosler gave credit to Berardi for the dedication he has shown since the German first arrived at Thorp Arch.
"It's good news for the football club. I said it from day one, Gaetano took (his) challenge on. He got fitter, by the week and by the month," Rosler said. "In general, I think Gaetano deserves this contract. He's a very stable performer and I'm looking forward to working with him in the next two years."
The Swiss defender has been a mainstay in the new manager's plans at Elland Road, while his new and improved deal suggests that his importance in Rosler's plans isn't likely to diminish any time soon.
After being rested at MK Dons last time out, Berardi is expected to go straight back into Leeds' line-up for the tough away game at Middlesbrough this weekend.
A win at the Riverside for the Whites could potentially take them into a play-off position, while if the game is to go in the favour of Aitor Karanka's team, Middlesbrough would extend their winning streak to six in all competitions, while piling even more pressure on league leaders Brighton.
