"Watching him is like watching a Rocky movie or something," said Colin Edwards last October. "He's definitely going to be a threat when he comes to MotoGP."
But his fellow Moto2 riders and Race Direction have been more critical of Marquez's all-action approach.
Marquez was penalised late last season for a nasty collision with Ratthapark Wilairot, after the practice chequered flag had been waved at Phillip Island.
Thomas Luthi was then left furious after a close last-lap victory pass sent him off track at the opening 2012 round in Qatar, while Catalunya saw a nasty clash with Pol Espargaro - for which Marquez was initially penalised by Race Direction, although the penalty was later overturned.
Despite such incidents, none of the MotoGP riders questioned at Mugello mentioned any objections to Marquez's riding. The only concern was of a more technical nature, raised by Dovizioso.
“I will be interested to see what Marquez can do in the next two or three years. He is so fast and so strong. I have a good relationship with him,” began the Monster Yamaha Tech 3 rider.
“I am interested because his style is quite particular and I want to see how he will ride the MotoGP. I think there is a big difference, it looks like in Moto2 you can't work a lot the bike, but in MotoGP you have to.”
Marquez won the 2010 125cc World Championship for Red Bull Ajo Derbi and is presently 43-points clear in the Moto2 title race for the CatalunyaCaixa Repsol (Suter) team.
Marquez finished runner-up to Stefan Bradl in his injury-shortened 2011 debut Moto2 season, with his Sepang eye injury - caused by falling on an unmarked section of wet track - also forcing him to miss most of winter testing.
