In one week's time, the 2017 summer transfer window will come to a close.It's been a pretty hectic couple of months, with Premier League spending recently breaking the previous record of £1.18 billion.Alvaro Morata, Romelu Lukaku and Alexandre Lacazette have all joined new clubs for a combined £190 million, while Mohamed Salah and Kyle Walker also completed big-money moves.But the biggest transfer story has undoubtedly been Neymar to Paris Saint-Germain, who splashed a world-record £198 million earlier this month to sign the Brazilian from Barcelona.It was expected Paul Pogba's £89 million move to Manchester United last year wouldn't be surpassed for quite some time, yet PSG decided to absolutely obliterate it.And there could be more to come.PSG are reportedly plotting another huge move for Monaco's Kylian Mbappe, who is valued by his club at £160 million.Money isn't a concern for Unai Emery's side and so they're prepared to meet Monaco's sky-high demands to sign Europe's - if not the world's - most exciting teenager.There were also rumours of PSG signing Mbappe on loan, but it would appear they're ready to take their total spend for the summer up to £400 million.Financial Fair Play (FFP) rules could yet have something to say about the Parisians spending a near world-record sum for the second time in one summer, but they appear determined to get the deal done.Mbappe wants a move, too, and you can hardly blame him considering the wages he's being offered to play at the Parc des Princes.According to Sky Sports' Kaveh Solhekol, PSG want to give Mbappe a 2000% rise on his current £16,000-per-week contract at Monaco with mind-blowing weekly wages of £320,000.To put that amount into perspective, Real Madrid - who also want to sign the France international - are 'only' willing to offer £120,000-per-week.

No words can describe how ridiculous PSG's proposal is. Mbappe doesn't turn 19 until December, yet he's about to become one of the world's highest paid players.

Football fans are certainly in shock about Mbappe's potential wage packet, as you can see in the following Twitter reaction.

Football and FFP is officially corrupt.

Neymar's £198 million transfer to PSG has started a snowball effect that can't be stopped, as evidenced by Mbappe's prospective move and Barcelona's pursuit of Philippe Coutinho.

Where the latter is concerned, Liverpool are expected to reject a £136 million bid for their Brazilian playmaker, which is just absurd.
