Arsenal's majority shareholder Stan Kroenke has bought up another 22 shares in the club, increasing his overall stake to 67.09 percent.
A statement from the London Stock Exchange showed Kroenke paid £28,000 per share and now controls 41,743 shares in total.
That share price values his own 67 percent stake at nearly £1.17 billion, and the club as a whole at around £1.7bn.
Kroenke last year turned down a bid from minority owner Alisher Usmanov -- who controls a 30 percent stake -- that valued the club at around £2bn.
Kroenke then reportedly tried unsuccessfully to buy up the shares of Usmanov, who issued a statement in October saying he was not involved in any discussions with the American.
Most of the remaining three percent of Arsenal shares are held by private individuals and life-long fans.
