The Chilean has had little rest over the last year, having starred for Arsenal last season and then guided Chile to Copa America glory in the summer.
Competing in that tournament meant Sanchez did not enjoy a proper holiday like most players and Arsene Wenger is cautious of potentially pushing him too far and causing either injury or burnout.
And so the Frenchman will hand his prize asset a rest in the next few weeks to help the Chilean recharge his batteries according to the Mirror.
It could prove to be a wise move for the Gunners as well, with them currently in the midst of an injury crisis that has threatened to derail their potential title challenge this season.
The side has lost a number of their stars in recent weeks, with Theo Walcott, Alex Oxlade-Chamberlain and Hector Bellerin all having been ruled out with injuries.
Losing Sanchez for a similar period could be devastating given his importance to the side, and Wenger is right to want avoid such a situation if it is in his power.
