The UEFA Champions League and Europa League return midweek, and a pair of young American stars headline the action for this week’s Americans Abroad.

After earning a substitute appearance over the weekend in a loss to RB Leipzig, Christian Pulisic and Borussia Dortmund face off with Apoel in a must-win UEFA Champions League match on Tuesday. Thus far, the German leaders have dropped matches to Real Madrid and Tottenham, and dropped points on Tuesday could knock them out of the race for a knockout round spot.

On Thursday, Matt Miazga and Viesse face Europa League action and a match with Belgian side Zulte-Waregem. The two teams have lost their opening matchups, giving both sides work to do to catch up to Lazio and Nice.

Elsewhere, Aaron Schoenfeld also faces a Europa League clash while Jonathan Gonzalez headlines a full slate of Liga MX matches.
