The Switzerland international started the season wearing the captain’s armband for the 1-0 win at Newcastle, but missed the subsequent victory over Burnley through injury.
Xhaka was restored to the starting line-up for the defeat at Liverpool during which Arsenal’s midfield was pulled all over the place by Jurgen Klopp’s relentless red machine, before conceding a needless penalty during last weekend’s north London derby.
Arsenal appeared destined for a second successive defeat when Xhaka went to ground and clattered into Son Heung-min, allowing Harry Kane the chance to convert from the penalty spot.
Alexandre Lacazette brought Arsenal back into the contest on the stroke of half time and Arsenal earned a creditable point when Aubameyang prodded home from close range following an astute Matteo Guendouzi pass.
Unai Emery defended Xhaka’s performance after the match, while the 26-year-old argued that his mistakes are always overstated while strikers appear to get off lightly.
He said: ‘In the London derby, I think we had a good game, I made a mistake with the penalty, yeah, but if you see the game we could have won.
‘We had a lot of chances, but this is football, nobody speaks about the chances, how many we missed, always they speak about mistakes. That’s a part of football.’
And Aubameyang appears to have taken note of those words, liking a post on Instagram in which a disgruntled fan appears to have had enough of Xhaka and his rushes of blood to the head.
