But with the Old Trafford side having already qualified by virtue of league position, their place for winning the cup passed down to the next team in the table without it.
West Ham join the Red Devils and Southampton as England's representatives in Europe's second tier competition.
Memories of Astra
They will enter at the third qualifying round stage this season, the same round in which they crashed out last year at the hands of Romanian minnows Astra Giurgiu.
But who might Slaven Bilic's side face this year and when?
Entering at this stage of the competition - there is one more two-legged play-off after that to make the Europa League proper - are the following:
- 5 domestic cup winners from associations 13–17
- 9 domestic league third-placed teams from associations 7–15
- 5 domestic league fourth-placed teams from associations 5–9
- 3 domestic league fifth-placed teams from associations 4–6 (League Cup winners for France)
- 3 domestic league sixth-placed teams from associations 1–3 (League Cup winners for England)
- 33 winners from second qualifying round
Who lies in wait
Other teams entering at the same stage as the Hammers include Celta Vigo, Saint-Étienne, Pandurii Târgu Jiu, Krasnodar, Viitorul Constanța, Hertha BSC, Spartak Moscow, İstanbul Başakşehir, Rapid Wien, Sassuolo, Vorskla Poltava, AEK Athens, Rijeka, Arouca, FC Oleksandriya, Rio Ave, AZ, Mladá Boleslav, Lille and Slovan Liberec.
They will be joined by the winners of the second qualifying round ties, the most notable of which are IFK Göteborg, Aberdeen, Hearts, Hibernian, FK Partizan, Maribor, Austria Wien, Slavia Prague and manager Slaven Bilic's boyhood club Hadjuk Split.
The draw for the third qualifying round is made on July 15th and the first leg will be played on July 28th with the second leg scheduled to take place on August 4th.
That second game comes three days before the Hammers are due to officially open their new 60,000 Olympic Stadium home with a prestige friendly against Italian giant Juventus.
