Five-time 500cc champion Mick Doohan believes Jorge Lorenzo will have "no excuses" not to beat to Marc Marquez at the factory Honda MotoGP team next season.
After two up-and-down seasons at Ducati, three-time MotoGP champion Lorenzo has switched to Honda for the 2019 campaign, and has ridden the manufacturer's bike in post-season testing at Valencia and Jerez.
He ended the Jerez test just 0.039 seconds slower than new team-mate Marquez and, although Lorenzo is unable to comment publicly on his progress aboard thebike until next year, Marquez reported the newcomer's initial feedback was similar to his own.
In a joint interview for Autosport and MotoGP.com, Doohan said Lorenzo will have nowhere to hide if he is slower than Marquez, and suggested Honda will be much more accommodating of Lorenzo's needs than Ducati.
Doohan said: "I think Lorenzo is in a complicated situation because he's got a lot of pressure, but on the other hand, that could be positive because the only thing he can do is to beat Marc with the same weapons.
"It's like when Eddie Lawson went to Honda and said that if Wayne Gardner used his same bike, he wouldn't be at his level. And Gardner arrived and won the championship [in 1987].
"I tend to think this is one of the reasons why Jorge has taken the challenge of riding next to Marc, to know if he is able to win against him.
"Jorge won't have any excuses because he will have the same resources as Marc.
"It remains to be seen how he adapts to Honda's working method, because Marc has been there for longer and knows everything perfectly.
"However, Jorge has a lot of experience and I think he will get used to it quickly. We won't hear again, 'If I had...'"
Doohan added the presence of Lorenzo - who replaces Dani Pedrosa - would spur five-time MotoGP champion Marquez on even more.
"What is clear is that Lorenzo's arrival will motivate Marc a lot," said Doohan.
"At no point of my career did I worry about who my team-mate was, and with Marc it is the same situation.
"If Lorenzo is faster than him, it won't be any different between that or Pedrosa, or another rider with a different bike.
"The growth will come from Honda's side, who will count on two good riders that are super-strong mentally, and they have very different riding styles.
"That will make them design and build a more competitive bike.
"Jorge will help Honda to get the bike to another level and will reveal the riders who complain."
