Borussia Dortmund's Serhou Guirassy scored a hat-trick in their 3-1 win over Barcelona, but it wasn't enough to overturn a 4-0 first-leg deficit. Barcelona progressed 5-3 on aggregate. Guirassy's impressive performance, however, made him the Champions League's top scorer this season with 13 goals. Barcelona will face either Inter Milan or Bayern Munich in the semifinals.
