Sanchez was a surprise starter as the Gunners made hard work of beating Doncaster 1-0 in their Carabao Cup third-round meeting on Wednesday night.
The Chile forward played the whole game, just as he did in last week's Europa League opener against Cologne.
Despite racking up plenty of game-time, Sanchez was only named on the bench in Sunday's battling draw at Chelsea and has yet to start a Premier League game this campaign. Sanchez is 11/4 to leave Arsenal in January, with Manchester City by far the likeliest destination according to the odds at 4/1.
Given Sanchez was close to leaving the Emirates Stadium in the summer - with a move to City failing to materialise on deadline day - and the fact he is out of contract at the end of the season, it had been insinuated in some quarters that Wenger was making a point.
But the Frenchman, whose side host West Brom on Monday, says there is nothing sinister in limiting Sanchez's appearances, pointing instead to an extended summer break and a niggling injury as an explanation.
"There is no disguised attitude on my side," he said.
"I just try to get him back to full fitness and for me the Europa League and the League Cup is important as well.
"I just try to give him competition and to get him back to his best, because I gave him a long holiday and after that long holiday this year he had a real rest. He came back not really fit, it took us time to get him back and then he got injured.
Despite his defence, Wenger said Sanchez would not be put on a pedestal over his Arsenal team-mates.
Asked if Sanchez was firmly in his plans, Wenger replied: "All the players are, he's not more than another.
"I said I chose the team at Chelsea who can be strong on the counter-attack and fight very hard and Sanchez could have played if he was 100 per cent fit at the start, but for me there's no real hierarchy."
Wenger made 11 changes to the side that played Chelsea but still fielded eight full internationals from the start against Doncaster, including Sanchez and Theo Walcott - who hit the winner.
