Manchester City's social media managers enjoyed winding up Liverpool after their draw at West Ham.
The club's official account liked West Ham's full-time graphic as they became the latest side to take points off the Premier League leaders.
There was no escaping it once the Hammers drew the world's attention to the online thumbs-up from the champions.
City's actions come a week after Kyle Walker reposted a tweet celebrating Leicester City's 1-1 draw with Liverpool - actions which upset manager Jurgen Klopp.
The Reds manager said: "I am not sure what that says about us, it says something more about the other person.
"I never celebrated that another team dropped points or lost a game. For me that's not allowed.
"For supporters it is a little bit different, for people involved I don't understand."
