Ricciardo denied he had felt "unloved" at Red Bull, although Verstappen is held up as a champion-in-waiting at that team, and said there were no hard feelings.
The Spaniard's comments appeared to be at odds with Red Bull boss Christian Horner, who suggested after Ricciardo's decision that Alonso was not under consideration. I'm pretty sure I always said I was close to doing something, not necessarily with Red Bull.
"But I guess after years of going to the same factory - that kind of routine - I felt at times my enjoyment of the sport was coming a little bit numb at times". And now they say that - that they are loyal to their programme and their junior drivers. "It has been weird, it has been unfair to me. He apologized on email and hopefully he will apologize again this weekend".
What did Horner say about Alonso?
When asked if he saw any signs Ricciardo was growing frustrated at Red Bull, something he revealed was the case on Thursday, Verstappen said: "I don't know, I don't think so". I think Max is one of the best drivers on the grid at the moment, so of course I am only in my first season of Formula 1, still gaining experience but I think there is a great opportunity ahead of me.
"I'm not sure it would be the healthiest thing for the team for Fernando to join. So I think our preference is to continue to invest in youth than take a driver who is towards the end of his career".
Why did Alonso turn down Red Bull?
"Right now I am thinking that it is a goodbye, but life changes very quickly and life also taught me in the past how things may change in a couple of months' time or in years' time", said Alonso.
"I can only assume that maybe he doesn't believe in the Honda project or that Renault offered him a lot of money".
"I think a lot of people expected me to take the soft option and stay because they see me as a soft guy", Ricciardo said.
Red Bull are switching to McLaren's former engine partners Honda next year and Alonso had been strongly critical of the Japanese power units during their time together. The race begins at 2.10pm on Sunday, August 26.
