Statistically, according to this source, http://www.footballclubrankings.com/2013/01/the-best-football-stadiums-in-the-world-2013/, these stadiums have been the ten hardest to play at in the last few years:

1. Old Trafford (Manchester United
2. Santiago Bernabéu (Real Madrid)
3. Etihad Stadium (Manchester City)
4. Signal Iduna Park (Borussia Dortmund)
5. Donbass Arena (Shaktar Donetsk)
6. Stamford Bridge (Chelsea)
7. Turk Telekom Arena (Galatasaray)
8. Camp Nou (Barcelona)
9. Estádio do Dragão (FC Porto)
10. Juventus Stadium (Juventus)

What do you think? Agreed, or not? Why?

Agree about Galatasary, but I'm not too sure about the rest. It's hard to believe this considering that Celtic Park (Celtic FC) isn't in it.

Mestalla should be in that list...  I dont get why Old Trafford is in there. Man U almost seem to better away than home.

The Britannia Stadium is also a pretty hard place to play at

what do you mean by hard..?

@tdot2barca

The ratio of wins to losses and draws away teams receive when playing in that stadium.

So you are basically saying Juventus have the best at home record in European football?

if you want to visit hell then go to galatasaray game

ethihad shoudnt be there
camp nou shoudnt be that high in the list
juventus stadium shoudnt be there, why would it ever be the 1st? the 2 games they lost were there.
stamford bridge should be lower
emirates stadium has to be there
celtic park or whatever the name is should be there as well
signal iduna park should be in the top 3
fernerbache should also be considered in the list

What about Allianz arena?

@Tunais ethiad shouldn't be there!? Man City were practically unbeatable at home last season!

thats because of the players not the fans lol

britannia stadium should be there aswell

What about Anfield?

stamford bridge harder than allianz arena No way 

How should Camp Nou not be there? They should be first on the list! Name the last time Barcelona lost at home.

vs Real last year

@Dynastian Camp Nou is there, on number 3

what PuppetMaster said is very true... dont mistake the fact a team doesn't lose at home because of their fans and because of their team. Man city was a very good team but ethihad had nothing to do with it, barcelona is hard to tell because they hardly ever lose at camp nou but I think the stadium may help a little for them. 

where is Bayern Munich? tough place to win

@tuanis i wish the emirates could be here, but we are not especially better if not worse at home. We lost to chelsea and swansea this season and had many poor performances.

I'd say camp nou in la liga, etihad stadium in the EPL and borussia dortmund stadium in bundesliga.

allianz arena not sure about that after last year disaster
