I like how you try to rationalize their action. Just following the transfer news around Europe is enough to answer your question.
No, they didn't have 1st 2nd or 3rd target that suddenly became unavailable.
Actually the only midfielder that was heard for them is Carmaviga along with the leak that Rennes president asked 100m or more for him, so eventually shut their interest down.
Yes, they are on the market for a midfielder, and Wijnaldum is a decent player to cover the position. That's common knowledge.
They are not just wasting money, they are paying a football player, and they will receive a service for him.
But 'Why him' and 'Why now' are the questions that should tell you that what's happening is far from accidental
It's not irrelevant that they didn't move for him earlier.
How many times have you heard a transfer to fail after a team has reached personal agreement with a player, and failing in particular because another team intervened AFTER the event offering more money in order to hijack the agreement?
It's naive to overlook the succession of events.
PS1: With Frenkie, they did it differently. They didn't hijack a closed deal.
They offered him a contract after it had been known for months that Frenkie wants Barca and Barca wants Frenkie.
They took advantage of the slowness and complacency with which Barto board had not secured an agreement with the player until then, but their intentions were the same.
Let's steal another player that is set to join Barca
PS2:
Guys please.
I am not throwing generalities 'the whole world is against Barca' etc
I am talking specifically.
It's PSG, Kelaify, and it has happened many times to think it's accidental.
Just count the cases of players that PSG targeted and/or tried to sign after it was leaked in press that Barca are interested OR Barca has an agreement with.
It's on purpose
PS3:
People can be petty, very petty...
Even at high positions of power and authority that are associated with some status.
Why do you think we hijacked Malcom's transfer to Roma? Because he was some unbelieavable gem that we discovered after he had agreed deal with them?
He was not even in any list of potential targets.
Barto and his board were pretty petty people and could not get over the UCL debacle at Rome
