After Elliot Lee showed no mercy in destroying Ipswich Town with four goals in a 5-0 win at Rush Green, Development Squad coach Nick Haycock was left full of praise for the prolific striker.
Lee scored twice in each half as the young Hammers kept their good form going with a resounding friendly win.
Pelly Ruddock also netted as the home side racked up the goals against their demoralised opponents.
The front man's return to Development Squad action was a welcome one for Haycock who believed he could have scored even more.
He told West Ham TV: "We were just laughing about it in the tunnel because we thought he could have had eight goals today and he probably knows that.
"Elliot's a finisher and he's the type of forward who could miss two easy chances and still end up with a goal and that's the sign of a good striker.
"The other week against Manchester City he worked hard but didn't have any chances and sometimes that happens but when he gets chances he takes them."
The striker's first goal came courtesy of some good fortune as his free-kick deflected off the wall and spiralled into the goal.
And Lee must have thought it was lucky day as some lackadaisical defending allowed him to notch his second hat-trick of the season.
It was not just his goals which impressed Haycock though, with Lee's application and attitude also catching the boss's eye.
He said: "Elliot looked like he wanted to play today and that was the pleasing thing for me.
"Sometimes you can go up with the first team and come back down and think it's only a friendly but his attitude was top class.
"I sensed in the warm-up that he was up for it. I can look into Elliot's eyes and know what I'm going to get from him. He's a very honest player and he deserved his four goals today."
Haycock and his squad can now look ahead to their return to Barclays Under-21 Premier League action when they host Norwich at Rush Green on Friday 4 October.
The coach warned that their next opponents will provide a tough test but also warned Norwich that they will need to be on their game to stop the Hammers.
"Norwich will be a tough test they've got a good forward line and that will be a good test for our back four which have been playing well all season.
"Equally they'll have to cope with what we've got and the boys couldn't be going into it in a better frame of mind.
"Our form will only continue if the standards they set everyday are maintained so next week we won't be thinking of anything other than working on the things we need to do to become a really top team."
