Arsenal reached a 4-1 advantage over CSKA Moscow at Emirates in Europa League quarter-final match with Aaron Ramsey and Alexandre Lacazette getting two each.
However, there is troubling news for Arsenal fans regarding Mkhitaryan and Ospina injuries.
Henrikh Mkhitaryan who was injured as a result of clash with CSKA’s defender Georgi Shchennikov , picked up a knee knock and was substituted by Alex Ivobi with David Ospina having damaged his ankle.
According to manager Arsene Wenger, Mkhitaryan will miss Arsenal’s Premier League game with Southampton on Sunday, while Ospina will be out for up to three weeks.
"Mkhitaryan has a knee problem," Wenger told reporters in his post-match news conference.
"We don't know how bad it is. He will certainly be out for Sunday."
"He just moved back to make a save and sprained his ankle. There was no contact," Wenger said.
"The scan today was reassuring. He will be out for two to three weeks. Yesterday [Wednesday] we were scared for a very serious injury, but today the scan was reassuring."
