The Chile international forward has been struggling with a hamstring injury of late and missed last weekend’s clash against Aston Villa at the Emirates Stadium.
The Gunners did not miss Sanchez much against the Villans, though, as they eased to a comprehensive 5-0 victory in the Premier League encounter.
Wenger has now suggested that the former Barcelona star could miss the North London derby at White Hart Lane.
“The latest is that Alexis is not ready,” the Frenchman told Arsenal’s official website. “He is not far away, the Leicester game is a possibility. He is of course very difficult to keep quiet! He is training but it's light training.”
England international striker Danny Welbeck, though, is back in the squad after recovering from a thigh injury which had seen him sidelined for over a month.
“Welbeck is back in the group,” said Wenger. “Apart from that we have the same squad available as last week.”
On midfielder Jack Wilshere, Wenger stated: “Jack is back in full training next week, hopefully from Sunday.”
Impact for Tottenham?
Wenger has not ‘definitively’ ruled out Sanchez from Saturday’s game, but from his comments it appears that the Chilean will not feature against Spurs.
This will come as a huge boost to Tottenham, who will now be feeling more confident of winning the North London derby.
The 26-year-old former Udinese star has been Arsenal’s best player so far this season, scoring 12 goals and creating 56 chances in 21 Premier League appearances.
Sanchez has a pass accuracy of 77% and a shot accuracy of 67%, and has won 47% of the duels.
While Arsenal showed against Villa that they can win without Sanchez, taking on an in-form Spurs team without their star attacker will be very daunting.
Tottenham are a much better side than Villa and playing at home will also give them an advantage.
Perhaps Arsenal are already on the backfoot against Tottenham.
