Italy goes into Sunday's Euro 2008 quarterfinal against Spain knowing that their group stage form has made the world champion look like underdogs. Spain goes into the Vienna match on a roll, looking to extend its unbeaten run to 20 games after winning all three group matches - albeit with decreasing authority - and with its first team raring to go after a week's rest. In contrast, 2006 World Cup winner Italy limped over the line having been on the brink of an early exit against Romania after its introductory 3-0 thrashing by the Netherlands. But that all counts for nothing now as, apart from a couple of Italy suspensions, the teams start again with a clean slate. Spain certainly will not be making any assumptions after so often looking the business in the group stage only to quickly fall away in the knockout rounds. “This team have learned a lot since the World Cup,” said midfielder Xabi Alonso in reference to their charge through the early stages in 2006 that ended abruptly with defeat by France. “We were a young side then and now we know what these competitions are like.” A team tagged as “perennial under-achievers” have looked good so far. Their neat-passing midfielders have created chance after chance for strikers David Villa and Fernando Torres, who took plenty of them in a 4-1 win over Russia and a last-gasp 2-1 success against Sweden. The reserves then stepped in to beat Greece 2-1 in their final game. Italy, which rounded off the group stage with a 2-0 win over France, makes something of a habit of starting slowly but coming to the boil when it really matters. Like Germany, who shrugged off a group stage defeat by Croatia to beat Group A winner Portugal on Thursday, Italy will wipe from their minds that Dutch drubbing and the Romania draw, when only Gianluigi Buffon's late penalty save kept it in the tournament. Its pedigree demands that it reaches the knockout stages and, unlike the nervous Spaniards who get nose bleeds at the mere mention of the last four, once there it settles comfortably and plans for the final. The tough route in, however, has cost it heavily with suspensions for midfielders Gennaro Gattuso and Andrea Pirlo. Experienced pair Massimo Ambrosini and Mauro Camoranesi should replace them and though neither has the relentless destructive appetite of Gattuso nor the class of Pirlo they are both more ambitious in getting forward. Antonio Cassano is likely to start alongside Luca Toni up front but though it is not a pairing to strike fear into the heart of a top international defense, Toni does carry an aerial threat against a relatively small Spanish back four. Italy's defense has sorely missed injured captain Fabio Cannavaro, for his organization as much as his talent. On Sunday, its reshuffled, makeshift rearguard will have be 100 percent concentrated to deal with the movement and probing runs of Spain's midfield and attack. – Reuters __
