"I have a lot of respect for Lewis, but still it is different when you win seven world titles when you only had to fight with your teammate," two-time champion Alonso told De Telegraaf.
"Then I think a championship has less value than when you have fewer titles but have had to fight against other drivers with equal or even better material.
"In 2005 and 2006, I had a good start to the year myself and was able to create a lead. Then others might have had a better car, but I was able to manage that gap.
"I never had to fight with my teammate to win those titles. Nor did I see Max fighting with Sergio Perez or Alex Albon to win races.
"But Schumacher in particular fought with his teammate to become champion five times in a row and Hamilton fought with Nico Rosberg and Valtteri Bottas. That's different, I think."
Hamilton’s teammate in his first F1 season was Alonso and they have endured a tumultuous relationship, of which the latest chapter came at this year’s Belgian Grand Prix when they collided and the Spaniard called the Brit “an idiot”.
Alonso later said via social media, about his own previous comments: "Please, all the titles are amazing, well deserved and inspiring. Incomparable to each other and let’s enjoy champions and legends of our current time."
