Lionel Messi’s move to MLS continues to pay off for the league — and especially his club — both on and off the pitch.

Sunday’s Inter Miami-Dallas FC Leagues Cup match sold out in just 10 minutes after initially going on sale last week. The secondary market saw tickets to the match at the 20,000-seat Toyota Stadium being sold for as high as $20,000 — just the latest sign of Messi-mania in the U.S.

Soccer’s power brokers want more and more of Messi, too. Ares Management has acquired another significant equity stake in Inter Miami — this time for $75 million — bringing the self-proclaimed alternative-investment manager’s total money spent with the MLS club to $225 million.
