I don't know how stronger Red Bull will get really. They are already very solid and far ahead of Mercedes in the standings now. This is even Red Bull's limited upgraded version I mean. If they didn't get any punishment for last season then I can't imagine how much stronger they would have been.
Please include names and the site where you got the info... Thanks.
But if the said 'good Ferrari engineer' is close to Binotto, I wouldn't say it's a long shot that Red Bull actually hires Binotto to be their CTO to replace Adrian Newey who could retire after this season or the next. Binotto is a really good F1 car designer, if not one of the best in the history of F1. Not a good team principal tho. That one should be left to the likes of Horner.
Unfortunately I can't find the source now. I came across the news on Twitter and I can't remember the name of the profile shared it.
I don't think the engineer I talked about is close to be one of the best engineers in F1 history though. Binotto is indeed a great engineer. Ferrari should have benefited from his engineering skills instead of making him team principal. But this is Ferrari and it has become natural to see them making the bad calls most of the time these days.
Newey is absolutely one of the bests and I believe he is better than Binotto. Red Bull will really miss him. But at least Binotto would still be a great replacement for him.
