Despite going on Borussia Monchengladbach's tour of Turkey recently, former FC Twente man de Jong is resigned to leaving the club, with Alan Pardew set to finally end his long-running pursuit of the 24-year-old centre forward.
The news may serve as a blow to Papiss Cisse, who could be the odd man out as Pardew will look to use Loic Remy and the incoming de Jong as his primary strikers.
Turkish side Besiktas are reportedly interest in signing Cisse on loan, whilst some speculate that Cisse will be offered to Monchengladbach in a straight swap for Holland international de Jong, which would be a return to Germany for the Senegalese striker.
Cisse spent two successful years with Freiburg, hitting 39 goals in just 67 games, which led to his £9m switch to St. James' Park in 2012.
But whereas Cisse was a roaring success in the Bundesliga, de Jong has struggled to replicate the form he showed in Holland. With 59 goals in 119 games for Twente, de Jong became one of the hottest properties in Europe, eventually signing for Borussia Monchengladbach for a fee of £12.6m after the German side had qualified for the preliminary stages of the Champions League in 2012.
There were high expectations surrounding Lucien Favre's side, and more specifically, their new hitman de Jong – but the move hasn't come close to matching those expectations, as de Jong hit just eight goals in all competitions for Gladbach, whilst he remains goalless this season, being limited to the substitutes bench as a result of his poor transition from Dutch to German football.
De Jong's goalscoring ratio in Bundesliga football is almost one goal every eight games, compared to Cisse's record of better than one goal every other game.
The stats don't necessarily mean that de Jong will be a failure because his record in German football is worse than Cisse's was, but it's cause for concern.
With Newcastle bidding for European football once again under Pardew, de Jong will need to hit the ground running in the Premier League in order to repair his reputation.
Cisse's goalscoring run may have fizzled out over the last few months, but after a much better showing in Germany than de Jong, there must be concerns for Magpies fans that de Jong won't prove to be an upgrade over the recently struggling Cisse.
