The north London side suffered another bitter blow to their hopes of Champions League qualification on Saturday as they slumped to a 3-1 loss to West Brom at The Hawthorns.
Sanchez was substituted in the second half due to an ankle injury as Arsenal lost their fourth game in five Premier League outings.
The futures of both Sanchez and Mesut Ozil appear to be up in the air, with both players’ contract set to expire at the end of next season.
And former Tottenham manager Redknapp feels that Sanchez is clearly not happy with his current situation at Arsenal.
Speaking on BT Sport’s Premier League Tonight show, Redknapp said: “Sanchez is not happy – whether he likes the manager or not, it doesn’t look like it to me.
“They don’t look anywhere near a force.”
Next up for Arsenal is a crunch clash against top-four rivals Manchester City at The Emirates on 2 April as the Gunners look to claw their way back into the Champions League qualification spots.
