Neymar's arrival has also left many observers wondering why the club hasn't invested in other positions, since PSG's attacking force was clearly not a problem last season. Two of those goals came from Neymar.
While Barcelona has lifted the European Cup five times and won the FIFA Club World Cup three times, PSG is yet to win either prestigious competition. "Our biggest challenge is the Champions League, but there are other trophies too".
The transfer is more than double the previous world record set by Manchester United's capture of Paul Pogba from Juventus a year ago for 105 million euros, leaving many commentators aghast at the rampant inflation in football transfer fees.
He spent the last four seasons in Catalonia, notably winning two Spanish titles and the Champions League in 2015.
Al Khelaifi has dismissed such reports, however.
The transfer has been embroiled in controversy on most part with Spanish La Liga threatening to file complaint against PSG over the transfer and the possible abuse of the financial fair play (FFP) rules. "We have been very transparent".
However, the tricks Barcelona turned to get Neymar would leave an indelible stain on the club's holier-than-thou image.
In doing so, Neymar has become the world's most expensive player - with the £198m transfer smashing the previous record of £89m set by Paul Pogba when he moved to Manchester United from Juventus a year ago.
Supporters were filmed gathering outside Neymar's hotel in the early hours of Friday, ready to welcome the world's most expensive footballer.

When posters of the Brazilian, accompanied by the words "Welcome to a Paris Neymar Jr 10" were unveiled on windows of the flagship PSG club store, the crowd cheered.
"I was in a tense moment but life in football is very fast". "I don't think he is expensive because I think (the transfer) will pay more than we paid".
At a press conference held on Friday, Neymar said: 'The club has a very similar ambition to mine, I want a bigger challenge. "I want to dream bigger".
But Neymar told reporters: "I've done nothing bad".
" Before Neymar the value was $1 billion and today it is $1.5bn". The money was wasted and they didn't win a major trophy for five seasons.
Paris Saint-Germain didn't exactly handover the cash in a black suitcase and walk out with Neymar.
"PSG and Neymar have the option to go to Federation Internationale de Football Association with the request that Federation Internationale de Football Association give them a provisional transfer", Javier Ferrero, a specialist in sports law for the Senn Ferrero firm, told AFP.
