He already owns the Patriots, one of the most historic clubs in American football. He is a heavy investor in American soccer, operating the Revolution. In '17, he added esports to his portfolio when he acquired the Boston Uprising in the Overwatch League.
And now, reports out of Spain suggest Robert Kraft wants to acquire a 40 percent chunk of La Liga side Sevilla Futbol Club.
SportsBusiness.com quoted Spanish radio Cope that the deal is expected to be finalized this week. In addition, the Mundo Deportivo suggests there is a slight power struggle in Los Rojiblancos' boardroom.
The Revolution have not commented.
If the reports are true, Kraft is buying into a rather historic club. Since its formation in 1890, Sevilla has predominantly played its football in Spain's top flight since it was promoted to La Liga in 1934, with only seven years since spent relegated to the second division; Sevilla has been in the top flight continuously since 2001.
During the 2017-18 season, Sevilla finished seventh overall, along with a runners-up finish in the domestic knockout tournament, the Copa del Rey.
It won La Liga in 1945-46 for its only top-flight title (it hasn't finished higher than third since the 2008-09 season), and is a five-time winner of the Copa del Rey. It is also a five-time winner of the UEFA -- the European football confederation -- Europa League, which is the secondary continental club competition to the Champions League.
