United looked to be heading for a first defeat in the five matches since Carrick was appointed head coach, before a brilliant flicked finish from substitute Benjamin Sesko earned us a 1-1 draw in the sixth of seven added minutes.
Tomas Soucek's own clever effort had put West Ham ahead earlier in the second half, and the well-organised hosts limited the opportunities the Reds had to hit back.
But Carrick's men, naturally disappointed not to make it five wins on the spin come full-time, stayed in the fight and were rewarded late on, displaying spirit that our head coach picked out for praise post-match.
