In this episode, AFC Richmond is playing Tottenham Hotspur. Tottenham is the team that Ted Lasso "coached" when his character first appeared in the NBC Sports commercials back in 2013.
Right after the opening credits Ted crosses Liam and their exchange ends with a weird guffaw laugh from the latter. Earlier in the season he's mentioned as "laughing Liam" in a mocking way when Higgins is looking for a new office.
When Roy says to Ted: "I'm calling HR" Ted replies: "Yeah? Well, tell Mr. Pufnstuf I said hello". H.R. Pufnstuf (1969) was a children TV series originally broadcast in the US on 1969 with a main character by the same name. Reruns of the 17 episodes shot were kept on air for most of the 70's and 80's which is why Ted goes on to say "That is a joke for people born in the early to mid '70s".
Rebecca's sex buddy Luca is a nod to Hannah Waddingham's actual companion Gianluca Cugnetto (usually abbreviated to "Luca" in Italy).
The club badge is correct on the Sheffield Wednesday shirt but the shirt sponsor is fake.
