A clinical Croatia have hammered Turkey 3-0 in their Euro 2012 playoff first leg, while Republic of Ireland thrashed Estonia on Friday.
Hosts Turkey saw the majority of possession in Istanbul, but goals from Ivica Olic, Mario Mandzukic and Vedran Corluka gave Slaven Bilic s side a stranglehold on the tie.
Olic tapped into an open net after Corluka s cut-back on two minutes, and Mandzukic doubled their advantage after half an hour when he headed in Luka Modric s floated cross.
Turkey failed to break down a solid Croatian defence and the visitors made it 3-0 when Corluka headed in Darijo Srna s free-kick from the right.
Meanwhile, Ireland secured a resounding 4-0 away win over nine-man Estonia in Tallinn.
Robbie Keane s brace, along with goals from Keith Andrews and Jonathan Walters, saw Giovanni Trapattoni s men take advantage of Andrei Stepanov and Raio Piiroja s red cards.
Energetic midfielder Andrews header put them ahead on 13 minutes and Estonia s tough task was made more difficult when Stepanov picked up a second yellow card just after the half hour.
Walters on his first start made it 2-0 on 67 minutes when he nodded in Keane s pass, before the Los Angeles Galaxy forward got on the scoresheet himself with a tap-in.
Estonia captain Piiroja was shown a second yellow card soon after, before opposing skipper Keane wrapped up the win with a cool penalty in the 88th minute.
In other games, Bosnia and Herzegovina and Portugal played out a goalless draw in an uninspiring affair at Bilino Polje.
Portugal attacker Cristiano Ronaldo and Helder Postiga both squandered good chances, while Bosnia and Herzegovina substitute Vedad Ibisevic was the main culprit for the hosts.
The Czech Republic took the upper-hand in their tie against Montenegro after a 2-0 first-leg win in Prague.
Vaclav Pilar s brilliant 63rd-minute drive and a Tomas Sivok goal gave them an important victory at home.
The second legs of each of the ties will be played on Tuesday.
