There wasn't much in it, but we just didn't have enough to overhaul the Ferrari drivers - who were very quick throughout Saturday's running.
According to Technical Director James Allison, it looks set to be a close Bahrain GP and one that'll hopefully see Lewis charging his way through the field.
"Although we made a small step forward relative to our performance yesterday, we were disappointed to learn this afternoon that it was not enough to compete on level terms with Ferrari," James explained.
"However, we know from Friday's long runs in practice that we have good tyre degradation, and there is every reason to expect a close race tomorrow, especially for Valtteri who will start from the clean side of the grid.
"With Lewis, we will need to be quite imaginative with the strategy to allow him to recover from the gearbox penalty - but this is a circuit where overtaking is possible, although never easy, and which will offer opportunities to make progress by starting on the soft compound."
