Well, the made hard work of it but in the end the Hammers did what we expected via the excellent Mo Kudus by and large.
He was on the end of a James Ward corner forcing an own goal after the visitors had taken the lead before heading home a second from another James Ward-Prowse corner and Soucek finished things off with a fine headed third.
The Irons dominated the first half without really breaking down TSC buy were stunned early in the second half when Stanic scored following a disastrous piece of mis-control by Oggy.
The team looked really shaky for a while but Kudus looked a star in the making as the fightback began and subs Soucek and Antonio really got into a rapidly tiring Serbian outfit.
At the back Mavropanos looked good and went close with a headed effort on the TSC goal whilst Benrahma made things happen in one of his better games.
So off we go to Serbia and hopefully it will be easier out there than it was at the London Stadium at times.
We understand that Jarrod Bowen failed to make the squad as he has been ill for a couple of days and not trained.
