Update: West Ham are seeking the young fan in question, and are offering him a spot in the Directors' Box for an upcoming match.
FA Cup glory may not have been high on Big Sam's priority list at West Ham this season, but crashing out 5-0 to Championship side Nottingham Forest likely wasn't what the fans had envisioned. In fact, ITV caught one young supporter bawling after Forest's third goal.
You have to applaud that kind of passion. Hat tip to 101 Great Goals for the spot.
