The Chilean has struggled to find his best form since recovering from injury.
However he came into the new campaign worn out from his international exploits with Chile. After taking a while to get up to speed he scored in six consecutive games for club and country in September and October.
However his form again drifted and he then picked up an injury in November. Since returning to action he has struggled for his best form and has scored just once.
"He'll give everything in his locker, that's one thing we can say about Sanchez.
"It looked to be far easier for him at times before the injury. Now it is a little bit more difficult.
"He is just finding his way back into it. I think he will get there in time. He is a player who is so exciting.
"It's rustiness in some respects. When it starts to happen the floodgates open for players like that.
"One of the telling factors is the amount of praise his fellow team-mates give him when they do interviews. He's obviously this bright spark, an infectious and enthusiastic guy with all this skill all this energy.
"The type of player who, when the goals come back, they come back in abundance."
Sanchez can certainly be something of a streaky player and if he could get on one of his better run of forms right now it would be a huge boost to Arsenal.
A good run of form from the Chilean could inspire Arsenal to the Premier League title this season and the Gunners faithful will be hopeful that he can find his form in the coming weeks.
