Lewis Hamilton has conceded Mercedes has work to do if it is to stop Ferrari from securing pole position on home turf at Monza.
Ferrari ended Friday practice in Italy as the team to beat going into qualifying after Sebastian Vettel topped the timesheets in FP2 ahead of teammate Kimi Raikkonen. Hamilton could only manage third fastest, trailing his title rival by 0.287s.
Vettel ran out as the comfortable winner at last weekend's Belgian Grand Prix and Hamilton believes the pace deficit to Ferrari is the same as it was at Spa.
"I think it's the same, exactly the same,'' Hamilton said.
