Going into the World Cup break, morale was sky high in the red half of north London with Arsenal sitting five points clear at the top of the Premier League table.
While that fact remains the same, Arsenal could be going into the second half of the league season without an integral part of their squad in talismanic forward Gabriel Jesus. The £45million former Manchester City man has sustained an injury while away at the tournament with Brazil.
It is a clear case of every club manager's worst nightmare, with a star player jetting off on international duty mid-season before returning injured and unavailble. News first broke of Jesus suffering some kind of problem with his right knee that would initially see him ruled out for three weeks.
