London's "Arsenal" club will have to make an effort to keep their key players.

This time, the headlines feature the name of French national team defender Laurent Koscielny. The footballer is linked with three clubs.

The 28-year-old footballer is of interest to "Paris St. Germain," "Monaco," and "Bayern Munich."

A new contract will be offered to L. Koscielny by the team led by Arsene Wenger. Currently, the Frenchman earns £50,000 per week and his salary is planned to be increased to £90,000 per week.

L. Koscielny's future at the club will depend on how the end of the season goes for the "Arsenal" team.

Currently, the Frenchman has a contract with the "Gunners" valid until 2017, so potential buyers may have to pay more than £20 million for this player.
