Mercedes's drivers
Lewis Hamilton and
Valtteri Bottas have been giving their thoughts on Friday's action in Bahrain.
Hamilton who was fifth and fourth fastest in FP1 and FP2 respectively said:
"It's been a normal Friday, we've got through all our programme.
"It looks very close between all the teams and we definitely have got some work to do to try and see if we can eke out to be ahead of the others.
"The tyres have felt the best they've felt here in years; very stable and with less degradation. The track is great and it's amazing at night-time.
"The hospitality here is really second to none, it's an enjoyable stay and a great place to work."
Hamilton's teammate Valtteri Bottas was slightly faster in Bahrain finishing 2nd and 3rd, Bottas spoke following the day's sessions, saying:
"We could already see it today, you feel more grip with every single lap and the car balance is changing so we always had to make estimates for the next session and the next runs.
"It will be the same for tomorrow. Our main goal today was to get the softer compounds to work.
"On the SuperSoft we did pretty much the same time as on the Soft, so getting the most out of that compound is the key thing for tomorrow.
"The car feels okay, but we still need to find some pace, especially for a single lap. So we still have some work to do."
