Star to return for Arsenal against Newcastle United

Arsenal have not started the season as per the very high expectations of the supporters and they have only earned 4 points from their opening 3 PL fixtures (only a single point from the two home games).
The North Londoners have not adequately reinforced their squad in this season’s summer transfer window so far and right now face some major injury concerns as well with five players out.
The first choice central defensive partnership of Laurent Koscielny and Per Mertesacker was missing in the last game against Liverpool and manager Arsene Wenger opted to play Chambers and Paulista in the central defense. The duo looked shaky at the back against Liverpool’s marquee signing Christian Benteke.
According to reports, it is inevitable that the French international Koscielny will miss the game against Newcastle United with a back injury. However, Mertesacker was out because of illness and there are chances that the Big German might return.
As per the provided PhysioRoom link, Mertesacker should return for Arsenal on 29th August to face the magpies.
