Aleksandar Mitrovic was at the centre of controversy on Saturday, his 16th minute red card being the pivotal moment in the match.
A quarter of an hour of poor service and support from his teammates, as well as the Arsenal players crowding him whenever he got the ball and no whistle from the referee as he was clearly barged from behind by Koscielny.
The Newcastle striker then deliberately/accidentally making contact with Coquelin and Andre Marriner instantly waving a red card.
However, little sign of his latest sending off denting the confidence of 20 year old Aleksandar Mitrovic, the striker turning up in this eye-catching t-shirt for international duty.
Mitrovic joined up with the Serbian squad ahead of two matches in the next seven days.
They have a European qualifier(***) on Friday at home against Armenia, before then moving on to France for a friendly next Monday (7 September) when Mitrovic could potentially face Moussa Sissoko.
The Newcastle striker has 13 senior caps and one goal at international level but has now started to establish himself as first choice.
Mitrovic started the last two European Championship group matches against Portugal and Denmark, both defeats for Serbia.
(***In terms of European ‘qualification’, Mitrovic and Serbia already need snookers. Portugal lead their group with 12 points, then Denmark with 10, whilst Serbia are rock bottom with -2(minus!) points after they had three points deducted after the abandoned qualifier agaist Albania)
