Saints' squad have been warned "it's not pat yourself on the back time."

Despite a good win over then leaders Bristol City last weekend, Nigel Pearson's side remain deep in relegation trouble - particularly after Barnsley's surprise 3-0 victory over promotion hopefuls Watford in midweek.

Only three points separate the six teams who look set to battle it out for the third and final relegation place, of which Saints are one.

With results elsewhere proving so unpredictable, it's hard to know how many points it will take for survival.

Almost certainly it will be more than the 51 points Walsall went down with in 2004 - the most points accrued by a team relegated from the Championship in the last decade.

But what is clear is that Saints have to get some themselves because they can't rely on anybody else to do them any favours.

Pearson said: "Last weekend's gone now. We're back to getting ready for another game.

"We've got to be very careful it's not pat yourself on the back time - we played very well, it was a great result and we needed it.

"But now we're into four games left.

"It's very tight at the bottom and there's a number of sides like ourselves fighting to survive.

"We've got to make sure we do enough ourselves to stay in this division.

"Last week was very pleasing but it's one game, it's gone now and the most important game is the next one."

Pearson is still waiting to see whether Gregory Vignal will be available for tomorrow's trip to Charlton.

The French left back hobbled off just before half-time in the win over Bristol City with a hamstring strain.

He was still unable to train yesterday.

Vignal will be assessed with Andrew Surman on standby to start at left back after impressing in that position as a sub against Gary Johnson's men.

Jermaine Wright could provide another option there moving from right back with Alexander Ostlund available to come back in again after recovering from his latest hamstring problem.
