CAN BOTH HENRIK MKHITARTAN AND PIERRE EMIRICK PLAY FOR ARSENAL IN THE EUROPA LEAGUE?

The very big question every one is asking are both the footballers that Arsenal brought in the January transfer window, be eligible to play for Arsenal in the Europa League. Well actually speaking Henrik Mkhitarayan can play in the Europa League, as he was playing for Manchester United in the champion league. But he will not be allowed to wear the jersey number 7, seven which he has inherited from Alexis Sanchez, according to U.E.F.A rules two footballers can not wear the jersey with the same number and a different name in a single season, so he will wear jersey number 77 , seventy seven, in the Europa League match. But on the other hand the Gabon striker Pierre Emirik Abumeyang , will not be eligible to play for Arsenal in the Europa League , as he had played for Borussia Dortmund in the Europa League this year.
