West Ham United suffered a shock 2-1 Europa League third round qualifying defeat to Slovenian side NK Domzale on Thursday.
Matic Crnic put the hosts in front from the penalty spot, with 11 minutes on the clock, following a handball from Hammers debutant Havard Nordtveit.
However, the Londoners were awarded their own penalty seven minutes later and skipper Mark Noble slotted the ball home from the spot to make it 1-1.
Domzale came out flying in the second half and deservedly grabbed the lead through Crnic's second goal of the game in the 49th minute.
The hosts continued to dominate the rest of the second half and looked likelier to grab another goal, however, the game ended 2-1 and the Hammers will now have to overturn the deficit in the second leg of the qualifier at Olympic Stadium next Thursday.
