Kroenke believes owning 100% of the club will benefit Arsenal

Arsenal's majority shareholder Stan Kroenke has made a £600m offer to buy the whole of the club in a deal that would value the Gunners at £1.8bn.

The American billionaire owns 67% of Arsenal through his company KSE, which says Alisher Usmanov has agreed to sell his 30% stake in the club.

A KSE statement says taking the club private will help to further Arsenal's "strategy and ambitions".

The buy-out announcement was made to the London Stock exchange on Tuesday.

Despite his shareholding, Usmanov is not part of the board or the decision-making at Arsenal.

The metal magnate made a £1bn bid to buy the Emirates outfit in May 2017 but this was rejected by Kroenke.

The statement to the stock exchange added: "KSE's ambitions for the club are to see it competing consistently to win the Premier League and the Champions League, as well as the major trophies in the women's senior game and at youth level."

KSE said that under "its stewardship since 2011 the club has invested in major transfers, player contracts, analytics, senior non-playing football management employees" and it "expects the club to build on those investments".

Arsenal have a new manager in charge this season after Unai Emery took over from Arsene Wenger, who had been Gunners boss for 22 years.

In Wenger's final season, Arsenal finished sixth in the Premier League as they missed out on the Champions League but qualified for the group stages of the Europa League.

The Gunners start their Premier League campaign against champions Manchester City on Sunday.

'A dreadful day for Arsenal' - fans' reaction

While Kroenke says taking sole ownership will benefit the club, the Arsenal Supporters' Trust (AST) called the news "a dreadful day" for the Gunners.

"Stan Kroenke taking the club private will see the end of supporters owning shares in Arsenal and their role upholding custodianship values," said an AST statement.

AST added that by becoming the 100% owner, Kroenke would be able to take "detrimental actions" such as paying "management fees and dividends without any check or balance".

It added: "The AST is also extremely concerned to note that this purchase is being funded by a loan.

"The AST is wholly against this takeover which marks a very sad day for Arsenal football club."

Analysis - what does single ownership mean?

Rob Wilson, football finance expert at Sheffield Hallam University

There are two sides to this and from a fans' point of view you like to have a bit more transparency - when there is more than one person involved you get a broader discussion about what you should do, who you should buy and how much to spend on particular people.

When you have this single ownership, particularly when it will be set up in the United States, it lacks a bit of transparency.

There will be big dividends getting paid out from the football club as a profit maximising entity, but for Arsenal that's not really any different to what they have had for the past 10 or 15 years with Usmanov and back when Farhad Moshiri (former shareholder and Everton co-owner) was involved.

The only thing that concerns me is it's going to be a leverage buy-out, so he's going to have to borrow to be able to do it. Depending on which side of the fence you're on will determine whether you see that as a positive or a negative thing.

From a purely business point of view, it's not a bad model. It's like you or I buying a house, taking out a mortgage, if you maintain those payments against those loans or however you borrowed then it is not a problem.

While the leverage is there that would have to be paid back, I don't think it will limit the activity Arsenal will be able to undertake in the transfer market as the reality is in order to make that business profitable, you have to be finishing in the top four and going into European competition.

What are the details of the offer?

Kroenke will be raising the capital to take control of the club with £45m of his own money and borrowing £557m, which he says will not be against the club.

"The offer is not being funded by way of any debt finance (bank loans, payment in kind loans or other debt or quasi debt interest bearing obligations) for which the payment of interest on, repayment of, or security for any liability (contingent or otherwise) will depend on the business of Arsenal," said the statement.

In the offer document, external-link each of Arsenal's 62,217 shares are valued at at £29,419.64.

KSE currently has 41,743 of those, with Usmanov holding a stake of 18,695, which would be worth £550m under the offer.

Aquiring Usmanov's shares would move KSE past the 90% threshold whereby they could compulsorily be able to purchase the remaining 1,779 shares, which are valued at £52.3m.

Apart from Arsenal, Kroenke's "family portfolio" of assets also include NFL side Los Angeles Rams, the NBA's Denver Nuggets, the NHL outfit Colorado Avalanche, MLS side Colorado Rapids and Colorado Mammoth of the National Lacrosse League.
