Redknapp: Spurs boss has written off Gunners' hopes
The Gunners again missed the chance to close the gap on the league leaders on Wednesday night after being held by Spurs in a six-goal thriller at White Hart Lane.
Arsenal squandered a 3-1 lead against their arch rivals on the back of conceding a last-gasp leveller in Sunday's controversial draw at home to Liverpool.
Arsene Wenger's side are six points behind the Red Devils with just five league games remaining, although Sir Alex Ferguson's troops still have a trip to Emirates Stadium to come and a clash with Chelsea.
While teams have come from behind in the past to win titles, Redknapp believes the gap is too big for Arsenal to overcome and some now feel their mentality to succeed is to blame.
"I can't see Arsenal doing it," said Redknapp.
"Chelsea have gone second in the table after their win and that six-point gap between Arsenal and United is going to be very difficult to overhaul.
"Big leads have been turned around before, it wouldn't be the first time it has happened, and I don't want to be disrespectful - but I can't see them doing it.
"Yet Man United did not play that well against Newcastle on Tuesday. Chelsea might go on a terrific run and win every game.
"Man U have yet to play Arsenal and Chelsea so it's not impossible."
