The 28-year-old has repeatedly been linked with a move as he continues to stall over signing a new contract worth £300,000 a week.
Sanchez was unavailable for Friday’s dramatic 4-3 win over Leicester due to an abdominal strain but was still at Emirates Stadium, with Wenger continuing to rule out a transfer.
Manchester City are expected to test that resolve with an offer in excess of £50million before the window closes with Pep Guardiola keen to add further firepower to his attack.
Wenger is determined to ensure Sanchez honours the final year of his contract and believes there will be no complications in doing so given the additional motivation players have without the security of a long-term deal. Asked whether there was a danger of those who run down their contracts not giving their all, Wenger told beINsport: “You could say as well the other way round. The real question we have to answer is does the hunger index increase or decrease when you have a short contract or a long contract?
“I would be on the opposite side. That means the hunger index is higher when the contracts are shorter and it decreases naturally when the guys have long contracts.
“Contracts mean a lot. When you sign them as a club, you have to pay the money for the player if he performs or not. That gives you a huge responsibility and gives a guarantee of income to the players. Overall, I believe that it has a meaning.”
