Eintracht Frankfurt have made an offer for Chelsea winger Marko Marin.
The London Evening Standard says Eintracht Frankfurt want to rescue Marin from his disastrous spell at Chelsea and have lodged a £4m bid for the German international.
Chelsea signed Marin from Werder Bremen for £7m in 2012, but he failed to make an impression and started just five games in his debut season.
Last term he spent the whole campaign on loan at Sevilla, but the Spanish club decided not to turn it into a permanent move.
