David Moyes gave the kudos to Mohammed Kudus after the Ghana winger helped West Ham come from behind to beat Europa League minnows TSC Backa Topola 3-1.
The Hammers made heavy weather of the opening match of their latest European adventure on a stormy night in Stratford, but headers from £38million summer signing Kudus and substitute Tomas Soucek got the Hammers off to a winning start.
East London was hit by torrential rain before kick-off with water cascading through the roof onto the concourses at London Stadium.
“Tonight I thought we did enough to win although I didn’t think we were great in a lot of things we did,” said Moyes.
“The goal was probably our own doing but I didn’t fear the worst. It was a game where we had the lot of the ball and gave us a chance to see if we could do what teams have done to us lately.
“Kudus I thought started really brightly and came up with an important goal when I couldn’t really see where we would get one from.”
The Hammers had 78 per cent possession in the first half, which was the exact opposite of their stats during the recent smash-and-grab win at Brighton.
But Moyes got a taste of his own medicine when Ogbonna dawdled on the halfway line and Petar Sanic raced clear to give the Serbians a shock lead.
Kudus got his goal four minutes later and Soucek headed the third – with both coming from James Ward-Prowse corners – to finally ease West Ham nerves.
TSC coach Zarko Lazetic said: “We are disappointed and a little bit angry. We respect the other team, but we felt we definitely had an opportunity.
“Our tactic was to come and win and we feel sorry it didn’t happen.”
