Chelsea and Arsenal will fight it out in the coming days for Mapou Yanga-Mbiwa.
The versatile 23-year-old captained unfancied Montpellier to the French title in May.
He has a year left on his deal and would cost £7million.
Gunners boss Arsene Wenger is a long-time admirer but Chelsea sent scouts to watch Yanga-Mbiwa in Montpellier's 1-0 loss to Marseille on Sunday, says The Sun.
