German daily BILD have claimed that Manchester United have fully prepared a 40m bid which will be submitted later this week to Borussia Dortmund for Marco Reus. The German winger has been in superb form this season and has attracted interest from a number of big-money clubs, including the likes of Barcelona and Manchester United. And, whilst it is understood that Marco Reus would like to sign for La Liga giants Barca, a bid from Man United of 40m is likely to tempt Borussia Dortmund into a sale, prompting a potential move. Reus has scored 16 Bundesliga goals this season for Dortmund and has played a big part in their European success of late, helping them reach the Champions League final last season. United who are ready to make a number of summer changes, have reportedly prepared a massive 40m offer after being told the Bundesliga outfit would not accept anything less than 35m.
