Pep Guardiola could understand West Brom's frustration after Manchester City benefited from a marginal offside call in their 5-0 win at The Hawthorns on Tuesday.
Ilkay Gundogan scored twice in a rampant City display, but it was the second goal from Joao Cancelo that really took the match away from relegation-battling West Brom.
Home defenders appeared to stop playing when official Sian Massey-Ellis prematurely raised her flag while City were still on the attack, believing Bernardo Silva was offside.
Guardiola's side continued and scored in stunning fashion through Cancelo, his first Premier League strike awarded following a VAR review which showed Silva just onside.
It was the second consecutive league game in which City had benefited from such controversy, with Silva's opener against Aston Villa given despite Rodri retreating from an offside position to tackle Tyrone Mings.
Reports this week suggested the rule that allowed that contentious goal to stand would be tweaked, but the Baggies – despite Massey-Ellis' error – could only blame themselves for the slack defending that allowed Cancelo to capitalise.
Guardiola offered his sympathy after the match but explained City always play to the whistle, which did not sound until the ball hit the net.
"I can understand [West Brom being unhappy]," the City manager told BT Sport. "Now with VAR, in these situations, you have to follow the actions until the end.
"You never know what is going to happen. The goal is allowed, disallowed? Nobody knows, so you have to continue.
"Always we speak with the players: until the end of the action, continue because we don't know what happens."
West Brom were outclassed regardless of that call and have now conceded 29 home league goals this season, the most in Europe's top five leagues.
Of those, 22 have come in their past five matches at The Hawthorns, with Aston Villa in December 1935 the last team to ship as many over a five-game home stretch in England's top flight.
This was despite City playing without key men Kevin De Bruyne – out for up to six weeks – and Sergio Aguero, who is recovering from coronavirus.
After Gundogan's brace and Cancelo's controversial strike secured a three-goal lead inside half an hour, Riyad Mahrez and Raheem Sterling added to City's advantage either side of half-time.
Gundogan has scored seven league goals since December 15, making this the best scoring season of his career, but Guardiola believes any one of his players can profit when City are in this form.
"If you play good and everybody's involved in attack and defence and everybody can arrive and everybody can be in the position, everybody is able to score," he said.
City have now won both of their league games without De Bruyne this season, scoring six and conceding none.
Gundogan added: "We all try our best – it doesn't matter who's playing.
"Obviously we had a few players over the last week in different conditions, struggling from COVID or struggling with injuries. It's like the players get more and more ready to play.
"Obviously Kevin is a big miss for us for the next few games, but we have players who will get more game time over the next couple of games.
"We need them all. We need everyone to be involved, because everyone gives us a different quality, a different boost. We need to keep going."
