A 1-0 win for Astra saw the Romanian outfit knock Premier League side West Ham out of Europe.
West Ham manager Slaven Bilic was left "angry and frustrated" as his side crashed out of the Europa League after a 1-0 home defeat to Astra.
Following a 1-1 draw in the first leg, West Ham needed to win or for the game to finish scoreless to advance to the group stages of the tournament.
However, a Filipe Teixeira goal on the stroke of half-time saw Romanian minnows Astra claim a 1-0 win at the Olympic Stadium in London on Thursday, sealing a 2-1 aggregate victory.
