Enzo Maresca has inherited a squad still being reshaped following Pep Guardiola's departure, and one potential source of funds is Marmoush, who has struggled to hold down a regular starting role since arriving from Eintracht Frankfurt for around €70m in January 2025.
The 27-year-old started just eight Premier League matches last season, finding himself behind Erling Haaland in the pecking order for long spells, and has been the subject of transfer talk from several quarters as a result.
Tottenham have long been considered the leading contenders, but Newcastle United are also monitoring the situation closely, and could yet emerge as the best-placed of Marmoush's suitors given their financial position following a series of big sales this summer.
Manchester City are understood to be seeking a fee in the region of €60m-€65m for the forward, meaning both the Magpies and Spurs would need to show they mean business if they want to convince City to sanction a sale.
Marmoush and his representatives have previously indicated they want clarity from Maresca over his role before committing to any decision on his future, rather than pushing for an exit regardless of City's plans.
Should the move materialise, it would represent a rare case of two direct Premier League rivals competing for the same player from within the English top flight, at a moment when City are simultaneously working through their own incoming business following the expected departure of Rodri to Barcelona.
