The transfer window burst into life earlier this month when Gareth Bale and Thiago Alcantara completed sensational moves to the Premier League and there's still time left for a few more eyebrows to be raised as the top-flight's money men try to keep up with their rivals.
Liverpool moved quickly to bring in Thiago and Wolves striker Diogo Jota within a day of each other while Spurs announced the return of Bale and the capture of left-back Sergio Reguilon from Real Madrid.
Since then, Manchester City have splashed out on Ruben Dias and Chelsea are threatening to open the purse again despite already spending north of £240million bolstering their attacking options and signing a keeper. Now, Declan Rice is back on their radar.
With excitement set to build over the next week, what questions could be answered before this extended summer window closes at 11pm next Monday night?
Will United go back in for Jadon Sancho... and strengthen their defence?
After a dismal home defeat by Crystal Palace to open their Premier League campaign and a less-than-convicing win at Brighton, calls are growing louder for Manchester United to make their move in the transfer market. Former defenders Patrice Evra and Gary Neville have urged Ed Woodward to act, and even current left-back Luke Shaw has admitted they need investment.
Donny van de Beek struck a debut goal against Palace, but United looked tired and lethargic in their opener at Old Trafford and needed a late, late penalty to see off the Seagulls. Meanwhile, in Germany, Jadon Sancho ran the length of the pitch to set up Erling Haaland for a stunning Borussia Dortmund goal. A reminder of what could have been for Ole Gunnar Solskjaer. Things didn't quite go according to plan for Sancho and Co at Augsburg at the weekend but he is still the one United want.
There is talk that United have still not given up hope of prising Sancho away even as their hopes recede by the day. Either way they need to make a decision to go all in on the 20-year-old, or look elsewhere.
More pressing, the Red Devils desperately need to find a reliable partner for Harry Maguire as Victor Lindelof struggles.
Ole Gunnar Solskjaer said before and after the Brighton game that he had faith in his central defenders. Are you sure, Ole?

Will Dele Alli get his move from Spurs?
Being left at home for a Europa League qualifier at Lokomotiv Plovdiv is one thing, but then being left out of the squad for two Premier League games on the bounce is another.
Jose Mourinho is already moaning that his squad is too big, and it appears that former golden boy Alli is the man who could be sacrificed.
The decision to omit Alli - who is the subject of interest from Paris Saint-Germain - from the squad to face Southampton left his team-mates stunned and he was a notable absentee again when Spurs hosted Newcastle.
Alli is a long-term target for PSG, and the French champions are understood to have started to explore a possible move for the 24-year-old ahead of next week's deadline.
A season-long loan appears to be the most likely exit route if he leaves this summer.

Will Chelsea go for Declan Rice to fix their defence?
Chelsea were given a stark reminder of the gap between themselves and the top as they were swatted aside by champions Liverpool at Stamford Bridge on Sunday.
There's no real shame in losing to the
