Lewis Hamilton has again urged the McLaren team to push as much as possible in order to close the gap to Red Bull and Ferrari and Australia.

Hamilton secured third in the season-opener in Bahrain, although his run to third place was only possible following an issue for Sebastian Vettel - who lost pace while leading due to a spark plug failure.

With Vettel, Fernando Alonso and Felipe Massa having the edge over Hamilton at Sakhir, the Briton admitted that McLaren would need to make changes in order to close the gap - with upgrades needing to be brought forward if possible.

Rallying the troops in much the same way as he did last year, Hamilton urged McLaren to push hard back at the Woking factory and said that it was possible to close the gap to both Ferrari and Red Bull.

"Our pace in the race is not bad, not as bad as we first thought, but we still need to push really hard to close up to the Ferraris and Red Bulls," he was quoted by the Press Association. "If we keep pushing then I do feel we can close the gap to these guys, and hopefully be on the top of the podium.

"It's going to be difficult in such a short time frame to do that, so I need to go back now and give the team the biggest push. They are all pushing flat out as it is, but one extra person or two extra people can be more of a force.

"We need to get some more upgrades. It's that simple. We have them coming throughout the year, but we need to bring as many forward as possible to close the gap. We need to work out how to improve the low-speed downforce because that is really where they are taking the time away from us."
