Arsenal boss Arsene Wenger is keeping tabs on Lyon duo Alexandre Lacazette and Nabil Fekir - but the French giants are desperate to avoid losing both.
Lyon president Jean-Michel Aulas is reportedly open to letting one of his star players leave at the end of the season - his club have made big money in the past by cashing in on talented players - but he doesn't want to let both Arsenal targets leave in the same window.
Lacazette and Fekir have been revelations in Ligue 1 this season, as Lyon challenge defending champions Paris Saint Germain for the title.
Lacazette, 23, has five caps for France and has been sensational this season with 21 goals so far. He's also chipped in with five assists.
Fekir meanwhile, is an attacking midfielder who has eight goals and six assists for the French club.
French newspaper Le 10 Sport reports that Fekir's future is linked with Lacazette's, as should the striker leave Lyon then Aulas would block any move for Fekir.
As well as Arsenal, who have tracked both players this season, it's believed that Manchester City and PSG are monitoring developments.
Earlier this season, Aulas confirmed that he wants both star players to stay at the club if possible with a new ground on the horizon for Lyon.
"I want them to stay with us to play in our new stadium next year," Aulas said.
But between 2000 and 2010, Lyon were one of the shrewdest clubs in the transfer market when it came to buying and selling players. They sold Michael Essien to Chelsea, Karim Benzema to Real Madrid and Mahamadou Diarra to Real Madrid as well, all for big money. They replaced them with younger and cheaper alternatives.
It's a mantle that Porto have since taken up in Europe, the Portuguese side capitalising on the South American transfer market to keep themselves relevant in European competition.
