"We got through a large programme and did 151 laps which is a good sign of reliability".
"If we had used those (old tyres at the grand prix) it would have been worse". "It's very hard to undo the DNA of the vehicle and Monaco, Singapore and Budapest were all tracks where we underperformed and it's a great challenge for us to come back this year". McLaren was third-fastest with young reserve driver Lando Norris.
The Austrian said: "Valtteri deserved to win in Baku and could even have won the last two". Last season they were off the pace in Monaco, with Hamilton failing to make it out of Q2 and finishing seventh after being unable to work enough heat into his tyres.
Bottas, whose future beyond 2018 remains uncertain, told reporters after Sunday's race: "I think this year I've been meeting more or less my targets with the performance for the beginning of the year".
"I'm looking forward to Monaco; hopefully we can take some of the things we've learned onto there".
The team confirmed their job sheet included data collection in order to correlate performance between the wind tunnel and track after recent auto improvements, set-up work, plus focus on engine development. After initial investigations, Haas chose to end its running for the day after 76 laps, though the team ended up fourth on the timing screens as a result of a hypersoft tire run in the morning session. Despite winning in Spain after one victory in the opening four grands prix a year ago, it did not turn out to be the race that kick-started his season.More news: Government to take control of East Coast Main Line from Stagecoach Group

"I'm always on the worrying side".
It is a race where the pole-sitter often wins - it has happened on 20 of the previous 27 occasions - and, fresh from his victory in Azerbaijan, the Mercedes driver will be confident of maximum points again.
Valtteri Bottas was second, securing Mercedes' first one-two of the season.
"It was not a good day, but it's important these days that you understand why and what's missing for the next races. But I wasn't", he said. "There were quite a lot of things going on, with gathering data and trying to get on top of our issues". "It feels like a long time since we had a 1-2 finish, so there's definitely a measure of relief in how we asserted ourselves today", said Mercedes team boss Toto Wolff.
Giovinazzi ran 148 laps on Wednesday, the most of the 13 drivers who made it to the track. The teams for the change, including Ferrari and Mercedes, feel that the research that's been done by the new technical team at F1 headed by Ross Brawn justifies the modifications. "Race by race we're understanding the tyres more, which is a bit battle for everyone". Nicolas Latifi was the other driver on Pirelli duty, getting his second consecutive day in the Force India as a result.
