Henrikh Mkhitaryan’s sister has dropped a heavy hint that the Dortmund star will sign for Arsenal this summer – by following the Gunners on LinkedIn, according to .

The Armenia international looks set to leave the Bundesliga giants this summer and both the Gunners and Manchester United are interested.

The 27-year-old is out of contract next summer and Dortmund chief Michael Zorc admitted the club will be forced into making a decision over the midfielder’s future this week.

Jose Mourinho is known to be a huge admirer of the former Shakhtar Donetsk star but Arsenal are thought to be leading the chase with the midfielder preferring a move to London.

With Mkhitaryan remaining tight-lipped over his future, the midfielder’s sister may just have let the cat out of the bag by recently following Arsenal on social networking site LinkedIn.

Monika Mkhitaryan works for UEFA and doesn’t follow a single football club on LinkedIn – other than Arsenal.
