Lyon director Bernard Lacombe is fearful about losing Arsenal and Liverpool target Alexandre Lacazette.
The striker has been in fine form once again this season and his tally of 24 league goals is only beaten by that of Paris Saint-Germain's Edinson Cavani.
Arsenal have now been linked with a move for the France international after failing with an approach last summer, while Liverpool are said to be interested in him too.
Such speculation has worried Lyon supremo Lacombe, who fears the French club could lose their star striker at the end of the season.
