Newcastle seem to be getting their transfer business in order this summer.
Various reports have linked them with the likes of Ross McCormack, Jack Colback and more, which is a refreshing change for a club criticised for its lack of transfer activity in recent windows.
Now, they've been linked with Dutchman De Jong once again. But this time they may have targeted the right brother.
Indeed, Ajax midfielder Siem de Jong has told a Dutch news outlet that the Magpies have held informal talks with his agent.
"I really do not know what I'll do next season. I have spoken with the club but nothing is sorted," he said. "Also with Newcastle United, where my brother played last time, they have had a little contact with my agent. There was contact before, but it's nothing concrete. Newcastle is a great club."
It could, then, be a case of Newcastle trading one brother for another - a swap well worth making.
The other De Jong in question is, of course, Luuk, who moved to St. James' Park on loan in January. But the 23-year-old hadn't scored in 14 games before joining the Magpies - and embarked on another 12 goalless games since.
The Dutchman did register an assist and was generally seen as a bright spark on-field, showing particular efficiency in holding up the ball and linking with other strikers.
But a striker's job, at the end of the day, is to score goals - and Newcastle are seemingly set to refuse the option of taking De Jong on board full-time.
His brother added: "I do not know if he'll be there. He is employed by [Borussia] Monchengladbach and has not received a contract offer from Newcastle."
Instead, if Siem is to be believed, Newcastle could be trading Luuk for a family member two years his senior - and a man previously earmarked as a replacement for Yohan Cabaye.
Captain of Ajax and an international with the Netherlands (although not in their World Cup squad) De Jong will offer Alan Pardew's side considerable experience in midfield. He could well be an option worth pursuing.
