Yeah look at the examples of Atletico/Dortmund.
They both would be happy to have our squad problems like no good RB back up, or no back up for Yaya etc, yet they doing better in CL than us.
We simply arent getting the best out of our team, thats what stopping us mostly. We can improve things with new signings yes, but if they wont play their best as a team tactically/mentally, we wont be really successful in CL. Last year and this year too we had again tactical problems and mentality problems as well. (Barca too, thats why they failed later, Bayern too thats why they were humiliated by Real, so it happens with other big teams too just still it matters when it happens, 1/8 finals or group stage or 1/2 finals...)
Pelle did perform usually really well iweth big underdogs (Villarreal/Malaga) and probably reached their limit with them, but with lot better squads he had a dissapointment year with Real in CL, while this season exiting vs last few years worst Barca can only be seen improvement because before that Mancini's CL group fiascos were total joke campaigns...
(Both year squads lot weaker than us finished ahead of us like Napoli, Ajax, not mentioning the EL where D. Kijev and Sporting stopped us...).
Yeah we did not have much luck with the CL draws, but what was Napoli thinking when they got in a group with Bayern, City, Villarreal. They probably though ohh fuck thats it, we are done...
(No one expected Villarreal be that weak, as they finished on CL spot in Spain the season before logically, and ended up relegated from La Liga in the 2011-2012 season, thats how bad they were end of the season...)
This year was our best year in CL so far, but if we meet Atletico or Real and not Barca it could have been lot uglier and
the 4-1 loss vs Barca was hardly nice on its own...
Everytime we started CL we had lot more potential compared to that what we reached.
Now next season we should really go to the semi finals at least. Or 1/4 finals but only lose in an extremely close tie, like the Chelsea-PSG was 3-3 and away goals decided...
