What does Kroenke's purchase mean for Arsenal?
Shortly after Stan Kroenke started buying shares in Arsenal, the club's Old Etonian chairman Peter Hill-Wood famously remarked that he didn't want the American's "sort" involved in the north London outfit.
At a time when the rest of the Premier League's big four was falling into the hands of wealthy foreign backers, Hill-Wood and Arsenal took pride in being different.
Not any more. On Monday, the last domino fell. Arsenal, the Bank of England club, are now another franchise in an American sports tycoon's portfolio.
So will this make any real difference?

For some time now, there has been a sense that Stan Kroenke was Arsenal's future. He first bought shares in the club back in 2007, acquiring just under 10%, and spent around £200m to become the club's biggest shareholder before Monday's announcement.
In the process, he has seen off the challenge of a rival foreign investor, the Russian-based businessman Alisher Usmanov, who still holds a 27% stake in the Gunners.
With great uncertainty over the health of long-term director and shareholder Danny Fiszman and the commitment of Lady Nina Bracewell Smith, it was always a question of when not if Kroenke made his move for full control.
So, in splashing out a further £225m and launching a full mandatory takeover, Kroenke has ended one of the longest running takeover sagas in English football. The deal values the club's shares at around £730m, which, when added to the club's debt, gives you a total price of just under £900m.
To put that into perspective, that is only £100m more than what it cost the Glazer family to buy Manchester United back in 2005 and will put a slightly different perspective on their current valuation of the club, thought to be around £1.5bn.
Not known as "silent" Stan for nothing, Kroenke's public pronouncements are so rare that it is difficult to be sure of his long-term intentions for the club. It is also unknown whether he has used or will use debt financing to assume full control.
One can only judge him by his actions so far - and he has chosen to leave manager Arsene Wenger and the highly regarded British chief executive Ivan Gazidis to get on with running the club.
Supporters will, of course, want to know whether the takeover by a billionaire will mark a change in Wenger's prudent transfer policy and, ultimately, fortunes on the pitch.
Without a trophy since 2005, Wenger's team could still win the Premier League this season, although that is looking increasingly unlikely despite the victory against Blackpool on Sunday.
With the debt burden from the move to the Emirates Stadium now reduced to £147m from £350m and the club making healthy profits thanks to the ground's larger capacity, Wenger has had money to spend for some time now.
With Uefa's new financial fair play regulations coming down the track, the north London side are considered Michel Platini's model club.
The fact is that Wenger chooses not to spend the money he has at his disposal, preferring to develop young talent than to follow the spend or bust approach of Chelsea and Manchester City.
But will Kroenke's deeper pockets now lead to a rethink, especially if Arsenal end the season potless again?
