Vettel clocked a best lap of one minute and 21.105 seconds to outstrip Raikkonen by two-tenths of a second
Sebastian Vettel led a Ferrari one-two in a second practice session for the Italian Grand Prix.
The German clocked a best lap of one minute and 21.105 seconds to outstrip the Finn by two-tenths of a second at the high-speed Autodromo Nazionale.
Lewis Hamilton, who holds a 17-point championship lead over Vettel, finished third, 0.287 seconds slower than his title rival.
The British driver won from pole position last season, and has qualified first at Monza for the past four years, but, just as in Belgium last weekend, Mercedes are on the back foot.
Ferrari may have not celebrated a win on home turf since Fernando Alonso took the chequered flag in 2010. But Vettel, who escaped without damage following a spin into the gravel at the Parabolica, insisted he does not feel any extra pressure to deliver in front of the expectant tifosi.
“We are in Italy, in the home country of Ferrari, and everybody, not only the Ferrari drivers, can feel and sense that there is something special going on,” he said.
“Myself and Kimi have the two most special seats this weekend, and I am looking forward to it.
“People forget that for the last five years, Mercedes have been absolutely dominant, so it is good to be up with them, and a match, but we cannot take anything for granted.”
