Panic struck at Manchester United when the Armenian FA announced Henrikh Mkhitaryan had suffered an injury on international duty.
A 10-day absence is what they predicted for the 27-year-old and whilst that's by no means a long lay-off, it's the fact he would potentially miss Saturday's Manchester derby that worried United officials most.
The Red Devils have plenty of cover on the flanks but not having their £26 million summer signing at their disposal for such a big game was a concern.

Various updates were provided in the aftermath, with Mkhitaryan himself revealing on Instagram how he wasn't sure if he would recover in time to face Manchester City.
"I continue extensively my rehabilitation, but I’m not sure yet if I will be fit for the derby this weekend," he wrote.

"I'm motivated as ever and plan to put all my energy to be in great shape as soon as possible."
However, in a press conference ahead of the heavyweight clash, Jose Mourinho gave United fans reason to be joyous by revealing Mkhitaryan is fit to feature.
He told MUTV: "He is available. I'm not saying he's ready to play 90 minutes but he's ready to try to help us."
Mourinho also confirmed his squad is at full strength.
"There are no injuries and everybody has returned safely and on time for at least one training session. Everybody is ready and wants to play, of course."
Great news for the Red Devils; bad news for City. United fans have since reacted to news of Mkhitaryan's return and, predictably, they're over the moon.
Asked for his view on just how important Saturday's clash at Old Trafford is, Mourinho gave a typically composed answer.
"I am normal," he said. "We are playing to try and win the title. When you do this there is no match more important than another one when it comes to this stage of the season."
And on derbies in general, the Portuguese added: "I know what a derby means for everyone; I've played derbies everywhere, in every country, in so many cities.
"I always want to be in the position of emotional control because for me it is just a game against a very good opponent. If you want to be successful and you want to win the game then we have to be at the top of our qualities."
