Italy warmed up for the European Championship in style with a 7-0 thrashing of San Marino in a friendly on Friday.
Roberto Mancini's side struggled to break down the minnows early on in Sardinia, but captain Federico Bernardeschi hammered them into a 31st minute lead before Sassuolo defender Gian Marco Ferrari added a second three minutes later on his debut.
A brilliant volley from Politano and a close-range finish by Pessina late on sealed a seventh straight win for Italy.
"The result was obvious, it was important to be aggressive and to play well with speed in our passing," Mancini told Rai Sport. "Some performances gave me something to think about [for the final Euros squad selection]. I've some very good players."
The Azzurri coach gave some of the fringe members of his provisional 33-man Euro 2020 squad a chance to impress as he looks to cut his selection to 26 before the tournament, but Italy struggled to make any inroads in the opening half hour.
Italy are now unbeaten in 26 matches under Mancini, the country's second longest run without losing, one ahead of Marcelo Lippi and only behind the great Vittorio Pozzo, whose side did not lose in 30 games between 1935 and 1939.
