Borussia Dortmund are prepared to sell Ilkay Gundogan.

Kicker says with his deal due to expire in 2016, BVB have made Gundogan an ultimatum: sign a new deal or be sold.

Manchester United and Juventus have been linked with Gundogan, who has returned to full fitness this season after recovering from long-term injury.

Just last month, Gundogan revealed: "Real Madrid made an offer for me but my club rejected it. At that time I still had two more seasons left on my contract. But also, my injury wrecked it all. I wasn't able to play for 14 months.

"Now I want to look towards the future and make up for lost time with sporting success. Playing abroad has always been one of my main objectives. If I do leave here one day, I'd like to play in Spain or England."
