Did Gundogan's girlfriend reveal his next club?

Cape Town - The girlfriend of Dortmund midfielder Ilkay Gundogan may have blown the lid of his next club!

Dortmund have already confirmed that Gundogan will exit the club in the summer after failing to agree to a new contract to stay in the Bundesliga.

The Germany international missed much of the first half of the 2014/15 campaign with a serious back injury, which has limited his involvement for Dortmund but has played an important role in the club's late season revival.

Manchester United are the favourites to land Gundogan's signature and fans of the club will be hoping that there is a link to his girlfriend's social media account and his next club.

The midfield maestro's girlfriend, Sila Sahin, may have leaked his next club after her mysteriousInstagram post.

Wo bin ich?

"Wo bin ich?" means "Where am I" in English...

Could Gundogan be turning out in Manchester United jersey after all next season?
