The Magpies have become the latest European team to run the rule over the Egyptian forward.
Marmoush is also being linked to Premier League giants Liverpool, possibly as a replacement for countryman Mohamed Salah.
Per Chronicle Live, Newcastle is joined by Arsenal, Chelsea, and Manchester City in wanting to sign Marmoush.
The 25-year-old is being scouted heavily by English clubs, as they try to see if he is the real deal.
His club Eintracht Frankfurt has priced Marmoush at around £50M, given he has scored 14 goals and has 10 assists so far this term.
