Dortmund’s chief executive Hans-Joachim Watzke told German outlet Ruhr Nachrichten that Arsenal had made a ‘first enquiry’ for the Gabon international, but he declined to comment on any figures involved.
However, another German outlet, football magazine Kicker, reported that Arsenal had lodged a bid circling the €50m mark, which they also say has not been accepted by Dortmund.
It is thought that Dortmund are likely to accept a bid somewhere around €60m, a fee that Kicker say Arsenal are prepared to offer.
