Tottenham manager Harry Redknapp remains concerned about the possibility of relegation after his team's six-match unbeaten league run came to an unexpected end.
Redknapp was left shell-shocked following goals in the last nine minutes from Benni McCarthy and substitute Andre Ooijer which gave Blackburn a vital victory.
Tottenham were in control after Robbie Keane scored from the spot in the 29th minute when Gael Givet was adjudged to have handled the ball following a cross from Aaron Lennon.
However the dismissal of Wilson Palacios in the 79th minute changed the face of the game and left Redknapp still shy of the magical 40-point mark.
He said: "We are not safe yet. Thirty eight points is not safe. It is still all to play for.
"When I arrived staying in the Premier League was the only thing that mattered. We have to make sure we do that first and foremost.
"The general performance was terrific, so to come away with nothing is unbelievable."
Redknapp rounded on referee Peter Walton, saying Palacios' red card was "farcical".
The midfielder was sent off after two challenges on susbstitute David Dunn in quick succession.
Redknapp continued: "It was farcical. He never touched him. I think Dunny was embarrassed as he got up and shook his hand and apologised.
"But the referee was not clever enough to see it. After that we did not defend well enough.
"We were much the better team and as good as we have played away from home. We were in complete control. There was no danger whatsoever.
"I have never felt so comfortable at 1-0 up. Then suddenly we come off losing 2-1. It was amazing. We play some good football but you have to finish teams off."
It was a superb comeback by Blackburn and stand-in striker Christopher Samba played a key role in a victory which boosts their hopes of beating the drop.
He was pushed up front in the second half as Jason Roberts suffered a foot injury and Morten Gamst Pedersen also pulled up with a calf problem.
Samba made a nuisance of himself and set up the equaliser in the 81st minute for McCarthy, who scored his 11th goal of the season.
Blackburn maintained the momentum and Ooijer sealed the points three minutes from time when goalkeeper Heurelho Gomes failed to deal with a corner from El-Hadji Diouf.
Diouf milked the moment and Gomes reacted angrily with team-mates forced to seperate the fueding duo.
Redknapp said he did not see the incident but quipped: "Diouf could start a row in an empty house."
Blackburn have now taken 11 points from a possible 18 and manager Sam Allardyce said: "We are closer now to the big 40 and we can have a nice couple of days.
"It is not so much about performances now but results. It is all about getting the three points. We are the team in form down the bottom end. We are on the rise."
Allardyce praised the contribution of Samba and added: "Injuries to Morten and Jason meant we had to put him up front.
"It paid off, though, for us. He was excellent and upset two good centre-halves.
"But we cannot afford Morten and Jason to be injured for too long. We have not got a lot to work with at the moment."
