On Tuesday evening, the 29-year-old held a sparring session in Manchester's Trafford Centre.
There he was put through his paces by trainer Shane McGuigan, son of his manager Barry.
"I'm the best figher in the UK," Frampton told Sky, "and the only way to prove that is by beating Scott Quigg."
While displaying his focus, he also joked with those who had gathered ringside to watch.
It's going to be an explosive fight when Carl Frampton and Scott Quigg finally meet in the ring.
Both camps had been locked in talks about the showdown but it was a live announcement at the beginning of November on Sky Sports that finally confirmed that the showdown was to go ahead.
Anticipation had reached fever pitch after Frampton successfully defended his IBF super bantamweight title against Alejandro Gonzalez Jr in Texas in July while Quigg stopped Kiko Martinez to retain the WBA version of the crown in Manchester on the same night.
Frampton takes on Scott Quigg on Saturday February 27 and will be shown on Sky Sports.
