Villa and Everton have done business with each other, Lewis Dobbin moving to Villa Park and Tim Iroegbunam joining the Toffees, each for reported fees of about £9m.
Villa have also sold Omari Kellyman to Chelsea for £19m two years after signing him from Derby for £600,000. The midfielder made six appearances for Villa.
Meanwhile, Chelsea defender Ian Maatsen, who spent the second half of last season on loan at Borussia Dortmund, has moved to Villa for £35m.
Douglas Luiz’s players-plus-cash transfer from Villa to Juventus went through on Sunday for £42.35m.
English winger Samuel Iling-Junior, 20, and Argentine midfielder Enzo Barrenechea, 23, moved in the opposite direction for about £18.5m.
Leicester – who are already facing one charge for an alleged PSR breach – were put under a transfer embargo by the English Football League (EFL) in March but that ended once they became a Premier League club, following the top flight’s annual general meeting (AGM) this month.
Chelsea have agreed a £30m deal for Kiernan Dewsbury-Hall, with the midfielder representing Leicester’s best sellable asset, given he came through the club’s academy and will generate pure profit.
The Blues sold 20-year-old forward Omari Hutchinson to newly promoted Ipswich Town for £20m.
Newcastle were busy too, selling winger Yankuba Minteh to Brighton for £30m and midfielder Elliot Anderson to Nottingham Forest for a reported £35m, while signing defender Lewis Hall from Chelsea for £28m.
