PSG are counting on Bayer Leverkusen making a quick sale for Moussa Diaby.

The winger joined Bayer from PSG last summer and could be on the move again just 12 months later.

Arsenal and Borussia Dortmund are both keen on Diaby, with Bayer aiming to double their money by selling for €30m.

And PSG will be due a windfall, with a 20 per cent sell on fee negotiated in the original deal. Should Diaby go at Bayer's price, it will mean €6m into the coffers of PSG.

Arsenal are regarded as favourites to land Diaby courtesy of their good relationship with his representatives.
