As per Gianluca di Marzio, Chelsea are set to sign Doue this summer for a reported fee of €7 million (£5.8m/$7.6m) with €2 million (£1.6m/$2.1m) in add-ons. However, the Blues will immediately send the defender back on loan to Ligue 1. However, he will not return to Rennes and will rather join Strasbourg, who share the same ownership group as Chelsea.
