It’s one year on but still hardly anyone can believe it – especially Barcelona fans.
The transfer changed world football overnight.
Sums that previously seemed absurd were no longer ridiculous – and vast amounts were suddenly common place.
From that day transfer records have been broken on almost a daily basis.
The transfer market itself is still paying the consequences of the event, with price inflation rising to the highest it has ever been.
A year later, it is not clear who won, if anyone did, as all parties are yet to achieve what they proposed they would at the time.
For Neymar, who wanted to flee from the shadow of Lionel Messi, it has been a mixed bag.
His stated aim was to become the world’s best player – but he has clearly fallen well short of that both at club and international level, where his World Cup will be more remembered for over-wrought theatrics than footballing skill.
For PSG, yes they did achieve the (far easier) target of winning Ligue 1 but their Champions League dreams fell well short – again.
And for Barcelona, they were thought to be the most affected yet they still managed to overcome their arch rival and win LaLiga last season.
But their Champions League ambitions also fell short – crushed in a 3-0 second leg loss to Roma in the quarter finals.
Replacing Neymar however has been a more difficult task.
The Brazilian was said to be the next heir to the Camp Nou once Messi had finished his journey and to this day, nobody has stepped up to fill that position.
In the past 12 months, Barca have spent 400m euros on signings and none of the replacements seem to be at the leadership level required by the club.
Ousmane Dembele was a fiasco in his first year, marked by constant injuries, and Philippe Coutinho, with all the skill that he possess, is not Neymar.
Once Neymar left, the fearsome attacking line-up of Messi, Luis Suarez and Neymar, known as the MSN, disappeared.
Barcelona, and Neymar, have never been the same since.
According to Spanish publication Sport, a fee of around €30m (£26.7m) has been agreed between the German and Spanish giants and the Chilean has also reached a verbal agreement with Barca.
Vidal, 31, has been linked with a move to Manchester United and Chelsea in recent months but both clubs looks set to miss out on his signature.
The Blaugrana have already completed three transfers this summer – Malcom, Clement Lenglet and Arthur – but Ernesto Valverde is keen to recruit more.
And their fourth signing through the door looks like it could be veteran midfielder Vidal.
Marc-André ter Stegen says it would be a honour to hold one of the vice-captaincy roles at Barcelona this season.
The No1 goalkeeper, who is preparing for his fifth season as a Barca player, has been tipped to be one of the vice-captains considering that Lionel Messi looks set to be named the new captain following the exit of Andres’ Iniesta.
“It’s something that the squad will decide, but it’s an honour that my name is being talked about for the captaincy position,” the German goalkeeper was quoted as saying by AS.
“It would be an honour to be one of the captains, of course it would. But for me it’s not the most important thing. We need more than four captains.”
