The Chilean forward continues to play on for club and country, despite the lingering threat of injury.
Former Tottenham Hotspur and West Ham United manager has urged Arsenal to resist the urge to rest Alexis Sánchez, despite the risk of burnout in North London.
Speaking in the London Evening Standard, the 69 year-old pundit urged The Gunners to just 'play him' as the Chilean has now become so vital to Redknapp's former North London rivals.
Arsenal's Alexis Sanchez
Arsene Wenger's side scraped a 2-2 draw in the UEFA Champions League versus Paris Saint-Germain at the Emirates Stadium on Wednesday night, with Arsenal now without a win over three games in all competitions.
Sanchez again seemed to lack his usual sharpness that has been so key to Arsenal's unbeaten run since the opening day of the season, but Redknapp says Wenger should just play Sanchez inspite of reservation of match-fitness.
In his Evening Standard column the former manager said: "[here] we are debating whether Sanchez needs a rest when he says he doesn't feel tired."
"Sanchez is so important to the way Arsenal play now — especially now that he is playing the centre-forward role — so Arsene Wenger probably feels it is more of a risk to rest him than to play him all the time."
Since arriving from Barcelona following the 2014 World Cup in Brazil, Alexis Sanchez has become a fan favourite in N5. In 110 appearances for the club, the forward has scored 50 goals, with six in the Premier League this term.

Leading the Arsenal for the majority of this term, The Gunners have had a greater cutting edge this campaign and has allowed the likes of Mesut Özil and Alex Iwobi to blossom behind Sanchez in the number nine role.
Talk has once more intensified of the 27 year-old suffering burn-out after with his hectic schedule. Concerns were sparked during the international break when the forward reportedly suffered a thigh injury on duty for Chile.
Those worries have seemingly been played down after his participation versus Uruguay - scoring twice. Despite playing versus Manchester United and PSG on Wednesday also, Sanchez played with leg strapping raising questions over his clean bill of health.
Harry Redknapp has refuted such talk, but did have a suggestion how to manage the Arsenal star's workload.
"The best way to manage Sanchez and a player like him is to start him and when you are 2-0 or 3-0 up, take him off", stated Redknapp, adding, "That way you use him regularly but keep him fresh."
Arsenal's Alexis Sanchez
With Arsenal labouring to three consecutive draws over the last 270 minutes of play, Arsene Wenger's side entertain a plucky AFC Bournemouth side on Sunday, in which Sanchez will be key.
Looking further ahead and with the festive schedule less than a month away, Arsenal fans everyone will be praying the clubs' well documented injury history does not claim their most vital talisman.
