After an eventful summer, domestic football has returned, and is in full swing. Saving a few, most heavyweights have started strongly in their respective leagues and are hovering in and around the top four spot.
All title aspirants hope to kick-start their campaigns in the best possible manner, winning every tie. And here, we look at four European who have maintained a perfect domestic record so far:
4. PSV Eindhoven
The Eredivisie outfit may not be as lofty as some of the other teams on our list, but they most definitely have earned the right to be placed amongst the elites. They were thrashed 4-0 in the Champions League by Barcelona, but have won all six of their league matches and are currently leading second-placed Ajax by five points.
3. Paris Saint-Germain
The Ligue 1 holders have gotten off to a flyer this season. Not only do they possess the most potent attacking roster in the league, they also have looked quite solid at the back. So far, they have registered six wins in as many fixtures and are heavily favoured to extend their record when they face Stade Reims on Thursday.
The defending Italian champions have once again got off to a blistering start in Serie A. Despite looking a couple notches below their usual standards, Juventus have bagged five wins in as many outings. New signing Cristiano Ronaldo now has three goals to his name and will look to add a couple more when the Bianconeri take on Bologna this Thursday.
Ruthless in the transfer window and immaculate in the league, Liverpool have taken the English Premier League by storm this season. They have won all six of their matches so far and have looked absolutely majestic throughout.
The Reds are two points ahead of second-placed Chelsea and will face their first big challenge of the season when they visit Stamford Bridge on Saturday.
