    BERLIN, June 23 (Xinhua) -- Flying Spain dominated Group H at 2006 FIFA World Cup Germany without big efforts to qualify for the knockout stages, toppling other three teams Ukraine, Tunisia and Saudi Arabia in convincing manners.

    With three straight wins and deep hidden potential, the Iberians seemed more than determined to shag their long-earned tag as perennial "Underachievers".

    In their opening match against Ukraine, Spain's juggernaut almost make the east European side spellbound. Xavi Alonso and David Villa made a stunning blitz, scoring two goals within 16 minutes to destroy their rivals' confidence.

    The "Matador" controlled the stage to produce some dazzling solo show and rounded off the night with 4-0.

    Spain's following match against Tunisia was not that emphatic, but they rallied from one goal down to seal a 3-1 victory thanks to Raul, Fernando Torres and Cesc Fabregas's contribution.

    Having secured a birth at the last 16, the Iberians relaxed a bit to narrowly down the Saudi Arabians 1-0 with their second choice line up.

    Spain have remained undefeated in all the 25 matches coached by Luis Aragones and are stepping well en route to the trophy.

    Spain will face strong challenge from former world and European champions France in the 1/8 finals, but they have enough reason to be optimistic with top players like Torres, Alonso, Xavi, Raul, Antonio Reyes and Carlos Puyol.

    Ukraine had a roller coaster experience. After troubled by a fiasco at the beginning in Spain's 4-0 show, they took revenge on the Saudis with a 4-0 victory to sharply boost the team's morale. Then they had a decisive 1-0 victory over Tunisia to advance to the elimination round.

    Ukraine boss Oleg Blokhin said he was very satisfied as the original goal had been achieved, and as it's the team's first ever World Cup tour, the success is even bigger.

    Blokhin's "Talisman" Andriy Shevchenko has picked his form after a serious injury, firing home a sharp header against Saudi Arabia and a penalty against Tunisia.

    Functional players like Andriy Voronin, Anatoliy Tymoschuk, Serhiy Rebrov and Andriy Rusol will be the east European's strength, but an unsteady back line may always be their itch.

    Ukraine will entertain Switzerland in the next round and that is undoubtedly a tough game.

    As for Roger Lemerre's Tunisia, the Germany memory would certainly be a bitter one. The "Carthage Eagles" labored out a 2-2 draw with Saudi Arabia before a brave match against Spain, in which they featured some fine counter-attacks and fluent short passes but finally failed.

    In the vital match with Ukraine, Tunisia were unlucky as their only hit man Zied Jaziri was sent off before the interval, and were punished by a disputable penalty in the second half.

    Saudi Arabia once again got a nightmare, grinding out only one point from three group matches and had to go home with bare hands.

    The Saudis could have notched three points in their 2-2 tie with Tunisia, only to lose concentration in the last few minutes. They were humiliated by hungry Ukraine with a 4-0 demolition in the second match.

    Then after an uninspiring defeat against Spain, Marcos Paqueta's men had to bid farewell to the tournament. The only thing in which they may find consolation is that this time they were not pounced by 8-0. Enditem
