Sanchez has faced an uncertain future at the Emirates Stadium over the past 12 months amid interest from Manchester City in the Chile worldwide.
Wenger had played a mildly rotated squad during the midweek.
And with West Bromwich Albion visiting the Emirates Stadium today, Wenger insisted the 28-year-old would only return to his first XI if his form justifies it.
There was also interest in Evans this summer.
Jack Wilshere, meanwhile, chose to stay at Arsenal and fight for his place despite entering the final year of his contract and Wenger has made it clear that the club offering him a new deal is dependent on the midfielder proving his fitness during the course of the campaign.

Though, Wenger was given the vote of confidence by the board and backed for another two seasons in which they will be looking to win the Europa League.
