Minnesota United is expected to complete the transfer of 18-year-old Uruguayan attacking midfielder Thomas Chacon before the summer transfer window closes Friday, a source told the Pioneer Press.

Minnesota’s courtship of Chacon was reported Friday, with the fast and creative prospect being known then as a target of the club. On Saturday, the deal became known to be nearing completion — while any agreement had yet to been signed.

United has extended a long-term deal to Chacon, with a “large” transfer fee with Uruguay top-flight club Danubio, a source said late Friday night. Chacon has started for Danubio and played for the Uruguay under-20 and U17 teams.

Besides finalizing the deal, a few other dominoes must fall before Chacon will be able to compete for the Loons.

Minnesota must buy down Designated Player Angelo Rodriguez’s salary to take him below the maximum budget charge of $530,000. The Colombian forward is currently making $667,000 in total compensation, according to the MLS players union.

For Rodriguez, the option to take him off the club’s list of the MLS-max three DPs was first mentioned as an option when he joined the club last summer. Darwin Quintero and Jan Gregus, United’s two other DPs, have higher salaries, making Rodriguez the best option to be bought down.

Also, Minnesota has seven filled international roster spots, so the Loons will need to trade with anther MLS club for a slot that Chacon would then be able to fill. The Loons using MLS budget funds as a trade asset seems likely.

In addition, Chacon will need to complete his immigration paperwork in order to be eligible to play in the United States. He might stay in his native South American country to do so before coming to Minnesota.

Chacon would be the third addition to Minnesota this transfer window, joining Finnish midfielder Robin Lod and French fullback Will Moimbe-Tahrat.
