This isn't really "the DDR revisited" so much as "the DDR 30 years on", effectively a series of 14 groundhopping trips covering the clubs in the last East German top flight. The problem with it is that the real interest is in the past, but too often the stories are of relatively mundane items such as one club's unusual scoreboard or another's leaning floodlights - these could be any clubs. The piece on Dynamo Berlin focuses mainly on how close the western club Hertha Berlin were, and doesn't really explore why people would support (or still support) the team of the Stasi. And a strange vignette about being a spy which takes up half the Chemnitz chapter didn't seem to make any real sense.
There are some interesting snippets when talking to former East German players - accounts of sudden defections and the difficulties some players faced adjusting to a new life after reunification - but they're too few. One interviewee, Uwe Karte, has "many [...] strange stories", but we don't really hear them. The only really amazing paragraph - this in a book on East Germany, a highly unusual place - when Axel Schulz, a three-times capped East German international, says that he wouldn't want to be a player "because with the the pressures of social media the players are watched all the time now."
The idea that someone who lived under the Stasi reckons Twitter is worse is a remarkable one. You'd imagine a book on a place like East Germany has to have more such eye-opening revelations, but this one doesn't. A bit of a missed chance really.
