Jese Rodriguez has fallen down the pecking order at PSG following Neymar's arrival
Hughes hopes to land the 24-year-old former Real Madrid forward on a season-long loan.
And his arrival would pave the way for fellow Spaniard Joselu to leave the Potteries and join Newcastle in a permanent deal.
Stoke are favourites to land Rodriguez, whose career has stalled despite a £22m switch from Madrid to Paris last summer, although they are still wary of last-minute bids from rivals.
Hughes is not afraid to take a chance on risky signings, having rescued the career of maverick West Ham new-boy Marko Arnautovic following his troubled spell at Inter Milan - and paid West Brom £12m for Saido Berahino.
Rodriguez was highly rated as a youngster at Real but his career was rocked by a serious knee injury three years ago and he never forced his way back into the Spanish giants’ plans.
