Vettel needs to feel consistency in his car to perform at his best. When things were inconsistent at Redbull, he had a poor showing against an hungry rookie eager to prove himself. That situation proves nothing. It certainly does not prove that Ricciado is better than Vettel at his best. I think Vettel would emerge when the Ferrari proves to be consistently fast and reliable. This is an opportunity for Leclerc to take some easy advantages and wins. But l think this would change very quickly when Vettel gets his head in the right place.
I certainly don't buy the comments that Vettel won four world title because he had the car to do it and there were no credible contenders to make his wins harder than it was. You could easily say the same for every world champion that has been. Vettel, like Hamilton and Ricciado, had a shaky start to the 2019 season. Hamilton has recovered from a brusing loss to Bottas at Australia. The Mercedes pair resumed the status quo when we arrived in Bahrain, with Bottas adrift by some margin. Vettel need to do the same at China at least. He struggled to get his setup to its optimum in Bahrain and was slower all weekend as a result. The same can be said for Ricciado who is having is arse kicked by Hulkenburg.
I would say, don't write off Vettel yet, he is going to get it right soon l hope.
