Vettel: We tried some things, but they didn't really work

Lewis Hamilton topped both the FP1 and FP2 standings for Mercedes, as the reigning champions continue to pull away from a rather helpless Ferrari.

Vettel ended FP2 in third-place, behind Hamilton and his team-mate Valtteri Bottas, with the German a huge 0.763s off the Brit at the top of the grid.

The Italian team endured a painful Spanish Grand Prix last time out, and they admitted back then that its SF90 has been a disappointment. Vettel has acknowledged that not much has changed in two weeks.

"We tried a lot of things, they didn't really work so it was not that productive," the German said. "Overall, we are struggling a bit, obviously lacking a bit of pace compared to Mercedes, struggling a bit to get the tyres to really work, so a bit of work ahead of us.

"It's a bit of everything, so not exactly what you'd like around here. You'd like to know what the car is going to do so you can anticipate a bit more. But I'm sure come Saturday, things should calm down. Maybe it's a bit warmer as well, it could help us."
