Marc Marquez must ease into life as a MotoGP rider and resist overreaching himself in an attempt to win too soon, according to 15-time world champion Giacomo Agostini.
The motorcycle legend tipped the 19-year-old Spaniard to continue his impressive trajectory up the grand prix racing ladder in 2013 provided he can resist the temptation to 'overdo' things.
Marquez led LCR Honda rider Stefan Bradl heading into the final three Moto2 rounds of 2011, only for his title bid to be derailed by a practice crash in Australia and a practice fall in Malaysia which forced him to miss the final two rounds.
He stayed in the category in 2012 and dominated proceedings, claiming nine victories and 14 podiums from the 17 races.
He also earned a spot in Honda's works MotoGP outfit, and has subsequently impressed in post-season testing, settling into a "good rhythm on the bike" after three days at Sepang.
Agostini said Marquez must give himself time to fully adapt to life in the premier class despite such an assured start.
"Marquez is impressing everyone," he told Gazzetta dello Sport.
"I hope he is guided in a good way, because to think you can win everything immediately is difficult: fruit needs time to get ripe.
"He'll do a great season, but he can't expect to have everything this year already.
"To move up from Moto2's 140 horse power to MotoGP's 240 is no stroll in the park. He must not overdo things."
