Portugal and Spain earned wins in League A Group 2 as the Nations League continued full steam ahead.
High-flying Norway, meanwhile, were held to a stalemate by Slovenia despite going a man down in the contest.
Portugal had Joao Cancelo and Goncalo Guedes to thank for their 2-0 win over the Czech Republic.
Cancelo put the 2019 champions in front in the 33rd minute blasting the ball past Czech goalkeeper Jindrich Stanek from a tight angle after good work on the right before Guedes struck.
Valencia forward found himself in space and tucked in from a similar position to Cancelo to double Portugal’s lead as Fernando Santos’s side tightened their grip on the top spot in the group with seven points from three matches.
Portugal will next travel to Switzerland in the Nations League tie, having sealed an emphatic 4-0 home victory in their previous meeting.
Spain earned their first win of the Nations League away from home as an early Pablo Sarabia earned them a 1-0 win in Switzerland.
Last year’s finalists dominated the game from the start but were only able to score once when Sarabia struck from close range in the 12th minute following a low cross by Marcos Llorente.
After a mistake by the Swiss defense, the Atletico Madrid winger found Sarabia ghosting in between two opponents inside the six-yard box and he scored with a first-time shot.
Spain now have five points from their opening three Group A2 matches and sits two behind leaders Portugal.
Switzerland have suffered three consecutive losses and are winless in their last five games since qualifying for this year’s World Cup.
Slovenia grabed their first points in Nations League Group B4 campaign as they held Norway to a 0-0 draw in Oslo.
Slovenia were reduced to 10 men in the 63rd minute when Blazic was shown a straight red card for bringing down Erling Haaland when he was through on goal, and Martin Odegaard hit the resulting free-kick against the crossbar.
Haaland failed to add to his tally of three goals in the competition, and Alexander Soerloth missed a great chance to grab all three points, firing over the bar in the 75th minute as the visitors hung on for a point.
The Norwegians host the Swedes on Sunday while Serbia travels to the bottom side Slovenia.
