Andreas Christensen has been one of the few unqualified success stories of this season's loan army, playing a key role in the heart of Borussia Mönchengladbach's defense at the tender age of just 19. While Gladbach have, at times, been very inconsistent, they're still well within striking distance of the Bundesliga's Champions League spots and Christensen is one of the big reasons for that.
Unfortunately, all that success also means that the loaning club will inevitably test the waters as far as a permanent transfer is concerned, especially after successfully using a similar strategy with Thorgan Hazard last season. In fact, it would appear that Gladbach are willing to break their own transfer record to do so this time, paying upwards of €15m for the center back's services. Gladbach's current record signing is €12m-man Luuk de Jong.
This isn't the first and probably isn't the last time either that we hear of such interest. And while Chelsea would be silly to sell the highly promising Danish international, if we do choose to it, if he's not slated to get a real chance with the first-team in the near future, a sale with a buy-back clause (in essence like a more useful loan) wouldn't be the worst thing in the world.
