Found something impressive yesterday. A YouTuber named Mr MarkCoos played away against Chelsea in his master league. His team is Southampton.
He must be using fluid formation where his players drop back deep when he is out of possession.
Still, some good defending. But sometimes you can keep the CPU at bay even when it is a really strong team. At other times I bet if he faces QPR the CPU may raise hell on his defence. This is what annoys me about PES - sometimes teams facing relegation play like world beaters, whereas sometimes you can beat a top team with ease. Just seems there's a bit of randomness about the Super Star level script.
BTW, it is funny that this guy has the Southampton original players but he still gone and bought Paccini for his team
As for the quality of PES 2015 itself, despite all its faults in term of scripting, AI cheating and limited editing, I think this is the best PES in terms of gameplay and fun since PES 6.
Seriously, I think during the entire PS3 generation, PES stank. It was totally lost - 2008 had a decent gameplay but was infested with frame rate issues, 2009 took too much of getting used to and was badly rigged on AI cheating, 2010 I didn't play at all, 2011 was fairly decent (the best of the bunch) but it got old fast, 2012 and 2013 were utter shite, and 2014 was a very messed up unfinished game albeit being playable and somewhat enjoyable again.
So to me it is a real surprise to read people wanting to go back to PES 2013

The AI was simply unplayable there and that whole "jockey" automatic R2 marking system was a pitiful joke (and even if you did everything the game asked you to, you'd still get turned inside out by any mediocre CPU attacker). On 2012 it was even worse.
Now with PES 2015 I really think Konami got a lot closer to the addictive gameplay fun of the old PS2 days. They need a bit of tweaking here and there, but defo on the right track IMO.
What bothers me the most, even more than AI script cheating, is the visual/environmental limitations. For a series that used to have a stadium editor, I cannot stomach the fact that they just gave us some 15 stadia around the world and to make matters worse have blocked some licensed stadia from use by other teams.
For instance, I would have loved to use La Bombonera as a setting for some Spanish teams like Atletico Madrid or Valencia, because the stadium has a similar look and feel to theirs in the game.
Moreoever, why not let us create stadia again, of all shapes and sizes?
It really gets on my tits to play away at Barcelona and get KONAMI Stadium as their home turf.
My La Liga ML offers a grand total of 5 different stadia... Estadio Del Nuevo Triunfo is home to about 60% of the teams, then there's Burg Stadium and Studio Orione (about 30%, and note that those were only added in a recent data pack!) and the few other teams left use grounds like KONAMI Stadium and Royal London Stadium.
This brings us right back to Winning Eleven 4 in 1999, which must have featured about the same amount of stadia. I think this is unacceptable.
As for the editing of kits and emblems, it's another more complex story... but it is also a source of frustration.
