Best club side ever - get your votes in

Wait what? there are people that seriously think the pool team is better than United's Team of Rooney, Ronaldo, Tevez, Scholes, Nani, Carrick, Vidic, Rio, Evra, VDS etc all at their peak?

There's only Salah for Tevez and perhaps Trent that get in that United team imo.
No chance salah gets ahead of tevez!
 
Surely, 2020 Bayern by Flick has to be somewhere in this conversation.

Flick left Bayern with one of the greatest winning records in modern football history.

During his tenure, Bayern lost just seven games and won seven trophies (Bundesliga twice, DFB-Pokal, Champions League, DFL-Supercup, UEFA Supercup, Club World Cup).

Bayern went undefeated in the 2019–20 Champions League, the first team in European/Champions League history to lift the trophy with a 100-per-cent win record, and won 23 matches in a row across all competitions between 16 February 2020 and 18 September 2020, a record in German professional football.

Flick also coached Bayern to a treble, the second treble in Bayern's history. Flick held one of the highest win rates in football history, winning 83% of his games and helped Bayern average 3.0 goals per game across all competitions.

Let's be real be here and not talk with tinted glasses.

Salah is miles ahead of tevez.
It's only tevez he would replace in that front line, Salah is a level below Rooney and two levels below Ronaldo in that 2008 set-up.
 
Our defence was „weaker“ in 99 compared to 2008 because our attack was „stronger“.
We played too attacking and open in 99, there is a reason we went behind so often. But the attack was so good that it could create (and convert) endless chances.

In 2008 we were much more compact and cautious, didn’t concede much but also scored less than in 99 both domestically and in Europe.

Yes, the two were very much inter-connected. And that cavalier attacking approach with exciting games like the 3-3 draws with Barcelona and come-backs against Juventus and Bayern definitely added to the allure of the '99 treble win, much as the 2008 team was fun to watch too.

Judging relative levels of 'greatness' among the many great teams over the years might depend on what's most valued. More one-sided dominance and control is certainly a form of greatness, but the back-and-forth games where both teams demonstrate their qualities can often feel more like how football should be in some ways, and maybe provides a greater celebration of football in general.
 
While it's impossible to really compare teams across generations because of fitness/technology and so forth - that Barca 10/11 was far and away the most unbeatable team I've ever seen. Dominant in a way that almost rendered the competition meaingingless. IMO that is the peak system/squad combo certainly in my lifetime.
