The Scotland under-21 international is currently on loan with The Shrimpers.
The Scotland Under-21 international left-back had been in great form for the Accies in his homeland and West Ham beat off plenty of opposition for his signature.
However the 21-year-old defender has struggled for first-team football at Upton Park and was loaned out to League One side Southend United last month after an injury to their regular in this position Ben Coker.
The move has been a hit for the player - who has featured three times for the club and recently scored his first goal in professional football against Shrewsbury Town.
He has been speaking to the Southend Echo this week about his time with The Shrimpers and seems happy with his stint at the club:
“It’s been going well for me so far but I don’t want to say too much because it’s only been three games.
“I just want to keep my feet on the ground and keep trying to do well.
“We have Colchester on Saturday and that’s a massive game for us.
“It will be my first derby with the club and I can’t wait to get out there to try and get the three points.”
Hendrie initially signed for the club on what was a 31-day loan deal but with the emergency loan window opening next week it will be no surprise if Phil Brown tries to keep Hendrie at Roots Hall for the rest of the season.
West Ham fans should keep an eye on his progress, as the Scotland under-21 international will have his eyes on first-team football at the Olympic Stadium.
