Bottas, who narrowly avoided getting stuck in the gravel at the end of FP1 after running wide at the Sachskurve, said he "cannot remember driving" in conditions like the heat drivers experienced in practice.
A year ago, Vettel was on the way to victory at Hockenheim before the first big mistake of his troubled period saw him crash out.
With that in mind, regular readers will know I always think second drivers are underrated and Pierre Gasly, for all the flak he has taken, was brilliant at Silverstone and is a driver with a proven track record. Him and the team have struggled. They also assessed various aero configurations, while simulating different phases of the race.
The 23-year-old Gasly is having a hard first season with Red Bull and has yet to secure a podium finish after 10 races.
By comparison, Vettel has no podiums in the past three races and four in 10 so far, with one pole position. He has one year left on his contract after this season, and questions are being asked as to whether he should be the team's No. 2 driver behind Charles Leclerc. "That one I am eager to watch out for", said 34-year-old Hamilton.
"There is still the driver that won four world championships, but he makes too many mistakes and has to find himself in some way" Baldisseri added.
"As I have said before, I am still very early in my career and I am sure there is a lot more I can learn and a lot for I can do better", he said.
"In terms of pace, some runs were a bit better than others, but our overall feeling is that in these temperatures we're probably sitting a little bit behind Ferrari".
"We have a new upgrade for the cooling systems so that should be more efficient - and should give hopefully quite a few degrees of margin, but I'm not sure anyone expected to be racing in 40 degrees".
"The pressure I put on myself after that is bigger than any external factors". Deeper analysis of the quickest times reveals a familiar pattern to previous races, with Ferrari holding an advantage on the sections of track where long straights dominate and Mercedes clawing back a good deal of that time in the slower sections. "We've got these hot races coming up, which are obviously not so easy for us so it's going to be a challenge". We need to understand what to do better when the conditions are cooler and to try and improve in these conditions. "Over all the years, I think we've maybe had 10 in a season, but never seven in the first 10 so it is definitely an outlier and something we are proud of".
Hamilton is now tied with Schumacher on four German GP wins and should he be triumphant this weekend, then he will have the all time F1 record for most victories in Germany.
