The Western Conference side agreed to pay the Union $250,000 in General Allocation Money, an international roster spot and $200k GAM in performance-based incentives, according to MLSsoccer.com.
The Earthquakes now hold three DPs, with Monteiro, Eduardo 'Chofis' Lopez and winger Cristian Espinoza. The move, however, opens up a DP roster spot for the Philadelphia Union, who currently have Mikael Uhre and Julian Carranza under the category.
Monteiro joins the California side after three years with the Union, where he managed nine goals and 21 assists in 75 regular-season appearances. He also formed part of the 2020 Philadelphia Union squad that lifted the Supporters’ Shield.
He is the latest intra-MLS addition to the Earthquakes’ roster since general manager Chris Leitch took over as interim GM last July upon Jesse Fioranelli's departure. The team has also brought in former Portland Timbers player Jeremy Ebobisse, midfielder Jan Gregus under the Re-Entry draft, and defender Francisco Calvo through free agency.
This deal stands as the Union’s second outgoing trade of the offseason, after sending striker Kacper Przybylko to the Chicago Fire for $1.15m General Allocation Money in late January.
