The Hoops frontman expects a challenging pre-season.
The 25-year old enjoyed a stellar season last term, bagging 40 goals, and will be keen to progress under the tutelage of Rodgers but accepts that there will be a period of adjustment.
“Once we get our fitness levels back up it will all be about getting used to the new style of play under Brendan Rodgers and how he wants us to go about things,” he told the Record.
“It’s going to be interesting to see what that will be like. The new manager will have his own regime, how he wants to go about things, and everybody will have to take that on board pretty quickly.
“But we’ve not sat down at length to discuss what his plans will be. When we do that it will be interesting to see what’s going to happen."
Excitement is building at Parkhead with the appointment of Rodgers and big things are expected after a disappointing spell under former boss Ronny Deila.
The Norwegian’s tenure was characterised by poor European showings and a failure to dominate on all domestic fronts despite the absence of a real challenge from Rangers.
Rodgers’ appointment comes as the Gers make their long-awaited return to the top flight and, as was proved by their Scottish Cup semi-final Old victory, there is not a huge amount to separate the Old Firm.
The former Liverpool manager will be expected to entertain the Parkhead faithful, overcome Rangers and qualify for the Champions League group stages and he will need the likes of Griffiths to take to his methods sooner rather than later if he is to be successful.
