City face Watford away in Sunday's final round of fixtures with Arsenal at home to Everton and Liverpool taking on already-relegated Middlesbrough at Anfield.
Guardiola said Wenger had little to complain about, with his side facing already-relegated Sunderland and Everton, who can not move from seventh, in their final two league games.
"I just think let's make sure we win the game".
"I answer for 20 years the question: 'Is the top four nothing special?' I don't know why, suddenly, it could become such a big problem [not to finish in the top four]".
"I felt he had something left still", said Wenger, who only made a decision to start Sanchez at 4pm on the day of the game.
"Sunderland fought and you want that in the Premier League - that's what you want from every team", the Frenchman added.More news: Lakers turn attention to scheduling workouts with top players
Sanchez picked up an injury on Saturday and Wenger was pessimistic about his chances of playing this evening.
Arsenal need one of their rivals to slip up to have a shot at Champions League qualification, but Wenger is pleased by the desire his team have showed in recent weeks, with the win at Stoke marking their third consecutive league victory. We set up to try and make it difficult for Arsenal and for long periods we did do but not only that but we created opportunities and the players worked really hard.
"Once he is on the pitch and gets the ball, he always becomes a devil and forgets the pain". Moyes said: "That's an insult to footballers". I think he believes his team are good enough to be at least in the top four and challenging for the title.
"In 2003, we lost the championship and I asked the players in pre-season, "Why did we lose the championship?'".
Sanchez was only passed fit to play hours before kick-off and, having reached 23 goals for the campaign, Wenger was full of praise for the man whose own future remains uncertain, with his contract at Arsenal expiring in the summer of 2018.
"We made 71 points (last season) and were second".
