Despite the troubles at Barcelona, and comparative successes of Bayern Munich and Juventus, it is still themselves and Real Madrid who lead the way for having the most feared forward line in Europe.
However, with the acquisitions of Neymar and Kylian Mbappe, Paris Saint-Germain have arguably leapfrogged both Bayern and the Old Lady to become the only side who realistically challenge Barcelona and Real Madrid.
However, is it still a two-way tussle between the Spanish giants, or have PSG spoilt the party to claim the crown of having the most feared forward line in Europe?
1 PSG: Kylian Mbappe, Edinson Cavani & Neymar
We might as well start with the Parisians as they have dominated the headlines during the transfer window.
The French moneybags broke the world record for Neymar, paying almost £200m for his services, whilst they also have an obligation to make Mbappe's loan move permanent for £165m.
Cavani himself cost PSG £58m when he signed in 2013. Whilst they may have the most expensive frontline, is it actually the best?
It is certainly filled with goals, excitement and potential, as Neymar is undoubtedly a future Ballon d'Or winner whilst Mbappe netted 26 goals for Monaco last season, despite his teenage years.
Cavani arguably has the best movement out of any striker in world football and knows where the goal is, having netted 93 times in 137 league games for PSG, despite playing second fiddle to Zlatan Ibrahimovic for many of those appearances.
It is a fluid front three, with each player capable of fulfilling all three roles, but the trio have never played together and will take time to get to know one another's games.
2 Barcelona: Ousmane Dembele, Luis Suarez & Lionel Messi
This title would have gone to Barcelona last season, but losing Neymar is cataclysmic both on and off the pitch.
Messi is the greatest player on the planet and Suarez is arguably the best striker. Not only that, but Dembele has already proven what a phenomenal talent he is and replaces the skill and speed that Neymar brought.
Despite both Messi and Suarez ageing, with the former dropping deeper towards midfield, it is still the most balanced forward line in Europe.
Dembele will provide the width and ability to get in behind his fullback on the left, allowing Messi to roam in from the right as he always does, whilst Suarez is a complete forward capable of dropping to link play or get in behind to finish ruthlessly.
This front three may not have too many years left, but irrespective of that, it's still one of the greatest ever.
3 Real Madrid: Marco Asensio, Karim Benzema & Cristiano Ronaldo
You may look at this selection and wonder where Gareth Bale is. However, the talent and form of Marco Asensio can't be ignored while Bale continues to struggle with injury.
Asensio is proving with every performance what a phenomenal talent he is, capable of scoring spectacular goals consistently, demonstrated by his brace against Valencia.
The Spaniard is also a mazy dribbler and can thread a pass through the eye of the needle. Add him to the Cristiano Ronaldo and Karim Benzema partnership and Madrid have an extraordinary forward line.
Ronaldo is still going toe-to-toe with Messi for the crown as the best player in the world, whilst Benzema is crucial to the way Madrid play, also netting a good amount of goals himself.
This forward line has intelligence, goals, creativity and physicality. In fact, it has everything and is a major reason Madrid have won three Champions League titles in the last four years.
Having a midfield including Luka Modric, Isco and Toni Kroos to supply them certainly helps.
