Europe's football clubs have spent almost €2.7 billion ($3.16bn) so far in this transfer window.
With the window closing shut on Monday, October 5, we can expect a few last-minute deals as well.
Some of the more eye-catching deals has seen Manchester City invest in a new centre-back.
Ruben Dias made his debut in Saturday's 1-1 draw with Leeds United and gave a good account of himself after joining from Benfica for £62 million with Nicolas Otamendi heading in the opposite direction.
It took Pep Guardiola's combined spending on defenders past the £400 million mark. Six of City's nine highest transfer fees have now been spent on defenders.
Sheffield United signed highly-rated young Liverpool forward Rhian Brewster for £23.5 million while Barcelona acquired American defender Sergino Dest from Ajax for a fee of £19.1 million.
