LONDON — The Russian tycoon Alisher Usmanov agreed on Tuesday to sell his 30 percent stake in Arsenal to the club’s majority owner, the American billionaire Stan Kroenke, an agreement that would end years of acrimony and values the English Premier League team at $2.3 billion.
Kroenke and Usmanov spent years fighting for supremacy at Arsenal, buying up shares whenever they became available, and the deal clears the way for Kroenke to take the club private, an action that Usmanov had long blocked by refusing to sell his shares.
Kroenke, whose family also owns several American sports franchises, including the Los Angeles Rams and the Denver Nuggets, gained the upper hand in July 2011, leaving Usmanov to do little more than complain from the sidelines or seethe privately in the luxury skybox he maintains at Arsenal’s stadium.
