			 "Winning two races will be fine. Three will be perfect. Four and 
			I run 100km without shoes to the Maranello hills," the BBC quoted 
			him as saying on the second day of testing at the Circuit de 
			Catalunya on Friday. 
			 
			Arrivabene, who took over as Ferrari boss in November, said the team 
			had made progress but fighting for the title and beating champions 
			Mercedes remained a tall order. 
			 
			Ferrari were top in three of the four days in Jerez and second 
			fastest on both days in Barcelona although times at this stage are 
			less important than consistency and getting in plenty of laps. 
			 
			Australian Daniel Ricciardo was fastest for Red Bull on Friday but 
			only 0.010 quicker than Ferrari's Kimi Raikkonen. 
			  
			
			  
			 
			While Ricciardo did 143 laps, Raikkonen completed 90. 
			 
			"It's clear the others have really stepped up their game," said 
			Mercedes driver Nico Rosberg who handed over to world champion team 
			mate Lewis Hamilton in the afternoon. 
			 
			"The lap times are surprising to us and it seems Ferrari has made 
			the biggest step at the moment." 
			 
			There is however a suspicion Mercedes are keeping their powder dry 
			for when it really counts, the season-opener in Australia on March 
			15. 
			 
			Neither Mercedes driver was on top form on Friday, with Rosberg 
			suffering lingering back pain from a trapped nerve and Hamilton 
			returning after a fever sidelined him on Thursday.

			Hamilton did 89 laps and was fifth fastest, Rosberg 66 and was 
			sixth. 
			 
			"I've felt better but I miss driving so I wanted to get in the car. 
			It's been good today to get out there and get some laps in," said 
			Hamilton. 
			 
			"The first test was just about completing loads of laps and today 
			was the same so I've not really started dialing the car into how I'd 
			like to perfect it...but it feels good, similar to last year but 
			better." 
			 
			McLaren managed 59 laps with double world champion Fernando Alonso, 
			despite ongoing engine concerns, while Britain's 2014 GP2 champion 
			Jolyon Palmer made his debut as Lotus test driver and was eighth 
			fastest.
