The long protracted transfer of Gareth Bale from Tottenham to Real Madrid is finally happening and when it does, this summer transfer window will really spark into life.
Further transfers will be triggered by this near world record deal, both at White Hart Lane and the Bernabeu, but also across Europe as several top clubs will feel the ripples of this signing.
Firstly and most obviously, this move will be a catalyst for further investment from Tottenham Hotspur.
Spurs have already splashed the cash with the purchases of Paulinho, Roberto Soldado, Etienne Capoue and Nacer Chadli, but once Bale completes his Spanish switch, the green light will be given for further spending.
Already in the pipeline are moves for Roma's Argentinian prodigy Erik Lamela, and highly rated Romanian defender Vlad Chiriches, for a combined fee of around £37 million.
However, once Bale joins the 'Galacticos' it is widely rumoured that Spurs will look to add a marquee signing.
They have already had Brazilian playmaker Willian snatched from their clutches by London rivals Chelsea, but plenty of other avenues appear open.
On Spurs' radar are Brazilian winger Hulk from Zenit St Petersburg, who Andre Villas-Boas will know from his time as Porto manager. There have also been rumoured moves for seemingly out of favour Chelsea attacking midfielder Juan Mata and Real Madrid's Angel Di Maria.
Spurs are also in the market for a left back, with both Fabio Coentrao and Federico Balzaretti rumoured targets.
The repercussions of this deal will also be felt in the Spanish capital. Real Madrid will have to find the funding for this move from somewhere, and considering they already owe Spurs money from last year’s Luka Modric deal, it's a fair assumption to say that Madrid at the moment cannot afford this deal. Therefore player exits are an almost inevitability.
Firstly Fabio Coentrao has indicated that he would like to leave for guaranteed first team football, with Spurs a potential destination.
However, it's in attacking midfield where most intrigue lies. With Bale added to Cristiano Ronaldo, Mesut Ozil, Angel Di Maria, Isco and Kaka, amongst others, it would seem likely that one or two of these players may be shown the exit door.
Ronaldo, it seems, will stay put for at least one more season, but the same cannot be said with such certainty for Ozil and Di Maria.
Ozil reacted angrily to being substituted on Monday night, and maybe the player sacrificed in order to include Bale. Ozil has been linked in recent days to both Manchester United and Arsenal.
With both English sides failing to add significantly during this window, they may well be enticed into offering the German international the chance to ply his trade in the Premier League.
The same can be said for Angel Di Maria, who's wing position looks particularly precarious at Madrid, and with Arsenal suffering injuries to both Alex Oxlade-Chamberlain and Lukas Podolski, a left wing position may well be open.
Also at Manchester United, neither Nani, Ashley Young, nor Antonio Valencia have performed to such a high standard that they can nail down either wing position.
Another potential departure from Real Madrid is Spanish goalkeeper Iker Casillas, dropped last season by Jose Mourinho; he thought he would be reinstated as number one under Carlo Ancelotti.
However, he has seen the Italian keep faith with Diego Lopez. Casillas as such may be looking to leave Real, with Arsenal again reportedly lining up a move.
However, Barcelona may well be interested, especially with Victor Valdes leaving at the end of next season. Moving between Real Madrid and Barcelona is not unprecedented, and for the sake of the Spanish national team, a move for Casillas may well occur.
Other teams to be affected from this domino effect will include AS Roma, who look set to lose Erik Lamela.
The Rome club look well-place to cope with the loss of the Argentine, by lining up a move for Serbia star Adem Ljajic from Fiorentina.
Chelsea may be brought in, in a variety of scenarios. Firstly Spurs could turn to Juan Mata and hope the relationship Mata shares with AVB would persuade the Spaniard to make the switch across London.
Should Madrid recoup some funds through the sale of certain players, they may again enter the market, this time for Liverpool's Luis Suarez.
At the moment, Suarez looks set to remain at Anfield after a move to Arsenal failed to materialise, however he may be more interested, should Madrid come knocking, and Liverpool may well be more inclined to sell their star man to a team from outside of the Premier League.
That potential Suarez deal could then raise question marks over Karim Benzema's future, with rumour abound that he is also on Arsene Wenger's last minute wish list.
These deals are all hypothetical of course, but one thing's for sure; the remaining days of this summer’s Transfer Window are going to be exciting.
