Champions League is already back underway and the Spanish quartet of clubs came away undefeated, with Atlético Madrid, Barcelona and Real Madrid winning three points a piece; and Sevilla finishing with a point after a goalless draw with Juventus.

Atlético beat Dutch side PSV Eindhoven on the road, while both Barça and Real won at home, 7-0 and 2-1 respectively.

Diego Simeone's rojiblancos squad started their quest for a third UCL final in four years in the Netherlands, earning a hard fought three points in typical Atleti fashion. Saul Ñiiguez, not even 20-years-old, showed why everyone around the Vicente Calderon is so high on the homegrown budding star. The youngster nailed home an acrobatic goal off a volley after his first attempt was blocked. Gabi found him with a corner cross, he struck it well and was fortunate enough to even catch the rebound after his unlucky first attempt.

The visitors had a scare as Eindhoven earned a debatable penalty, but Atlético goal keeper Jan Oblak was able to save it, and thus kept a clean sheet to earn a victory.

Barcelona hosted Scottish Premier team Celtic at the Camp Nou Tuesday evening, greeting them with a seven goal barrage. All three attackers of the MSN attacking trident scored for the home side, Lionel Messi notching a hat trick and Luis Suarez netting two of his own. Andres Iniesta earned some glory as well, sliding one home in the 59th minute.

After losing 2-1 to a newly promoted Alvés in league play, Barcelona were definitely angry, and unfortunately Celtic took the brunt of their frustrations. This time around, manager Luis Enrique trotted out his full compliment of players for his top starting XI. And it didn't take long, as Messi opened up the scoring in the game's third minute.

On Wednesday night at the Bernabeu however, the goals didn't come as fast. Hosting Sporting Lisbon, Real Madrid themselves didn't score until the 89th minute, tying the Portuguese visitors after they had drawn first blood in the 47th minute.

If Cristiano Ronaldo isn't yet at 100%, the rest of Europe should be scared once he finally arrives at full fitness. In only his second match back from injury, he drew the home side even with a free kick blasted by the keeper and into the top right corner of the goal. Alvaro Morata proved to be worth his buy-back clause and then some as he came on and headed home the winner in the fourth minute of stoppage time.

Real's depth won this one, as they had been subpar all game, and it was James Rodriguez and Alvaro Morata, two internationals who could and would start anywhere else besides maybe Barcelona, linked up for the game winner. James providing the cross, and Morata the finish.

This is why Real Madrid managers are under so much pressure, they are given every resource to run the table year in and year out.
