Celtic may have something unexpected in common with the Bundesliga giants.
Celtic manager Ronny Deila has enjoyed a wonderful debut campaign at the club, guiding his side to a domestic double and coming pretty close to an historic treble.
While that particular challenge proved too much for the Bhoys this season, there is still so much for them to be proud of, not that Deila is standing still if reports are to be believed.
According to a report from the Evening Telegraph Celtic are interested in signing Dundee United striker Nadir Ciftci this summer, while The Scotsman claimed the Scottish Premiership champions are also keen on luring John Souttar from Tannadice.
At 23 and 18 respectively, both players would be great additions to Deila's squad, with Ciftci adding more goal-threat to the side and Souttar a wonderful young talent who can play as either a centre-back or a defensive midfielder.
Of course United will have something to say about that, and they are likely to do all they can to keep the two players despite their contracts having just over a year to run. But following the signings of Gary Mackay-Steven and Stuart Armstrong from the club back in January, are we seeing a similar situation as the one in Germany, where Bayern Munich consistently sign or are linked to Borussia Dortmund’s best talent.
There is no surprise that a country’s top club will be keen to sign said country’s top talent, and of course United do not need to sell to Celtic just as Dortmund do not need to sell to Bayern.
But with each new United player linked with a move to Celtic Park, one cannot help but be reminded of the similar situation that has seen the likes of Robert Lewandowski and Mario Gotze swap one German club for another.
Not that Celtic fans will be complaining of course, and it is all part of the business of the game we so love, but United fans may react to each new headline with a growing trepidation.
