Of course he still can make it at any League, yet the coach and team must be settle in order to allow him to be HIM.
Like Klopp said recently, being Messi is not a big issue of when and why he'll do it, but the team must work like for instance Argentina does, to let him be.
And this doesn't mean just to pressure for him, but understand how to use him.
You can see it in Miami in this last game how easily he gives order, settles the attack, cleans the play, find spaces and accelerate the tempo only to most of times the play be fvck up by the fella that receives the ball making a bad pass, misscontrol it, holding it too much, etc...for instance in this last game he made the typical Alba connection with the kid on the left numerous times, I don't think the kid returned the ball even once.
PD: BTW Redondito Jr, played REALLY BAD, he must calm down and hear Messi more, while osition himself better and play more simple and accurate, the technique and physique is there.
In PSG I don't think Poch was the right coach to manage the three lads, nor Galthier that at least at first did it better.
Nowadays Luis Enrique in fact was a better choice since day one, knowing both Ney and Messi and dealing with a similar situation in Barca, while being a winner coach with a strong character that doesn't care about status that much.
His first season, he had a good season for an Elite player, a mediocre one for HIM. And this I think was due to:
1. Him being really sad about how things ended in Barca and really angry at Laporta specially. He wasn't there, he arrived without preparation, quite a mess.
2. He also arrived there trying to not be a disruptive force and I dunno if that is the best approach if you want first to save YOUR face and make a stand about your status. Angry Copa America/WC/against Madrid Messi was needed.
Letting Ney keeping the 10, letting know Mbappe he comes to sum, not to be THE guy and not arrive more in a "I'm Messi, this is how this has to be done", wasn't a good idea given current PSG's state.
Neither of the two took really advantage of him, while fighting with each other and this approach and the whole context created a grey scenario that wasn't what him and PSG needed.
Only in the second season, specially Mbappe, realized the advantage of having him behind. Yet, later Ney was injured and didn't help the three of them the abysmal drop in level of many of the rest in the team: from blunders from Donna, Marquinhos, Ramos and cia, to Verratti being a shadow of himself and for instance Vitinha that looked promising at first being annoyingly stupid most of the time. The reinforces and youngsters weren't even near of the level that they had to be and bar the mirage of the first stage prior to the WC (the three fellas were fantastique), the team was still mediocre as one.
3. This created another issue, particular to PSG. The lads (fans) NEED to feel respected and the world tends to annoyingly troll them to the max. After the WC, somehow they expected to see Messy Messi, the "anda palla bobo" angry version and that wasn't going to happen, yet wasn't necessary either and he became the scapegoat (the first season things were already broken in his relantionship with many of the fans, for various reasons).
Suddenly no matter how great he was playing, setting attacks, managing the team in the offensive, the talks always were about how he walked the pitch, how he wasn't fierce, etc...he never either give the Barras the hour of the day and this with the overall mediocre level of the rest of the team bar Mbappe (that trully connected with him in many instances) fvcked everything up. He still produced, one of the major reasons of why they won the League title with Mbappe, but they are obssessed with CL and after the departure from it, plus everything said above created a really bad scenario that already was fvcked up.
Lesser players like Lavezzi, Pastore, Ibra and Di Maria had a better connection with PSG fans due to the commitment of those to the "cause", Messi comitt only in a Pro level, not in a sentimental one, everything was broken to the core, plus didn't help to the overal atmosphere, the level of the rest of the team an its production on the pitch.
So many of the things said above can happen at other European club if the coach doesn't have a strong personality and the players understand that at the end of the day, if you let him do his thing, everyone will benefit, sthg that with all the mess PSG is since a decade, with their insane auto pressure to become a Powerhouse, was far from a great place to done things right.
With all things sad, it's silly and fanboyism to say that he was above Mbappe in production in those days in PSG, specially the first season, yet he was the most intelligent player that they had and produced a lot in consequence in the second, but he just wasn't fully there, PSG wasn't having any and everything was broken.The narrative of the Press didn't help either.
Sorry for the long rant
