Lyon chairman Jean-Michel Aulas has warned interested clubs that Alexandre Lacazetta will not come cheaply.
Aulas has fired out a warning shot to those clubs hoping to secure the services of Lacazette in the summer, saying the Ligue 1 top goal scorer will cost in excess of 50million.
Liverpool, Arsenal and Manchester United are all rumoured to be interested in bringing the Frenchman to the Premier League this summer while Ligue 1 champions Paris Saint-Germain are also said to be circling.
"Nothing is ever sure in football but we will do everything to keep Alexandre with us," Aulas told Canal+.
"50m would not be enough, that is not the price."
Lacazette scored 27 goals for Lyon this season.
