Southampton B team coach Dave Horseman bemoaned the mistakes made which ultimately cost his side despite a dominant display at West Ham.
West Ham took the lead against the run of play in the 26th minute after a strong Saints start, Mipo Odubeko finishing off a fast break counter to give the hosts the lead.
The hosts’ second came in the 38th minute, Odubeko once again the man to finish off the counter with an emphatic close-range finish.
Kazeem Olaigbe got Saints’ first just past the hour mark; Ryan Finnigan closing down the Hammers defence well before finding Olaigbe who made no mistake with a curled finish.
But any sort of comeback was quickly quashed by another West Ham counter twenty minutes from time, as Daniel Chesters made it three with a near-post finish.
“It’s a tough one to take because we started the game really well,” Horseman said, “and got a couple of half chances, a couple of shots on the angle and felt like we were dominating.
“We’ve given a really soft goal away and the momentum came away from us, it became a lot more even and they had a lot more chances.
“Then we started to build our momentum back, get a lot more possession, work them side-to-side, have a couple of deep runs and we thought we’re going to get back into it.
“We’ve pulled a goal back and were totally dominant second half. Then you think the equaliser was going to come which would’ve been totally deserved.
“So loads and loads of good bits in terms of performance, then dominant for large periods, but if you want to win games you can’t make these mistakes we’ve made against anybody.”
