The Bosman battle for Borussia Mönchengladbach striker Marcus Thuram is intensifying.

After refusing to leave last month, Thuram is set to run down his contract this season and leave as a free agent.

La Gazzetta dello Sport says Inter Milan have made a pre-contract offer worth €5m-a-year. However, the proposal is expected to flush out rivals.

Chelsea remain in the picture after a January attempt. In addition, Barcelona, Atletico Madrid and Bayern Munich are said to be monitoring the situation, but have not yet made an offer to Thuram.

The striker has scored 13 goals and provided four assists in 21 competitive games for Gladbach this season.
