David Moyes equalled his biggest win as West Ham manager despite not being at the London Stadium.
Moyes, self-isolating after his positive Covid-19 test, was in constant contact with the Hammers bench as they thrashed Wolves 4-0 in Sunday's Premier League contest.
Coach Stuart Pearce was up and down the stairs as he answered the phone to Moyes.
It did the trick as two goals from Jarrod Bowen and further strikes from Tomas Soucek and substitute Sebastien Haller secured West Ham's first points of the season in style.
Assistant boss Alan Irvine, standing in on the touchline again, said: "David was in communication with Stuart all the way through the game - quite a lot, in fact - and that information was passed down.
"The subs were David's, I certainly wasn't going to be doing anything. I relayed his messages to the players."
Irvine is making interim management simple, with West Ham scoring nine and conceding only one since he stepped in for the League Cup win over Hull.
"It's been enjoyable to be honest, from a selfish point of view to step up and deliver those messages to the players," added Irvine, who will be in charge again at Everton in Wednesday's League Cup tie. Moyes is due back in work on Thursday.
