If we manage to buy Arthur and Griezmann we are set to go for the next couple of years. We might only need to add another CB if Vermaelen leaves this summer but if he stays fit I would definitely keep him for another year.
Honestly I would rather try to bring Thiago back instead of bringing Arthur but the problem is off course his price tag and I don't believe Bayern would sell. Also problem with Thiago is that he is unbelievably injury prone.
From a summer of 22, only Umtiti was a success.
For every player whom we buy, chances are always roughly 2/3 that a player won't make it, won't fit etc.
Coutinho hasn't played a minute yet.
Dembele is raising some reasonable doubts already.
Nobody knows how to intengrate Griezmann into our team.
Mina hasn't played a minute in Europe. If he'll make it here, that we'll be a huuuge surprise.
Arthur, the same story.
On paper, it seems that we are set and that we are fine, but in reality always majority of players never reach expectations.
It is hard to say in this moment who will make and who won't.
But I am quite certain that we will buy 2-3 new attackers and 2-3 new midfielders in the next 5 years.
In fact, I am expecting that we will buy a new Cm each summer for the next 5 years, until one guy will fit perfectly.
In the last 3 years, we bought Arda, Gomes, Denis, Paulinho.
Now we bought Coutinho, we are close to signing Arthur.
Plus we had some attempts with La Masia guys Samper, Alena (Roberto, Rafinha).
In a team like Barca, except in Pep's era, nothing is set and we are never still.
Don't get emotionally involved in too many new signings, because I don't like to call these guys: longterm projects.
I like to call them hit and miss gamble, and just "attempts".
Mina, Arthur and similar guys, those are not longterm projects.
Those are cheap guys with a potential on whom it is worth to bet.
If they'll play good, we'll keep them.
If not, we'll just buy 2-3 new Minas and Arthurs in the next summer.
That's how things work at Barca.
So, imo, there is no way that we are "set" for the future.
We will always buy 3-4-5-6-7 players in every summer.
Again, except in Pep's era when we had a young and domestic team which was winning 88 trophies per season.
In all other times, we are just always buying like crazy and alwwys trying with these hit and miss transfers each summer.
