Bolton Wanderers boss Gary Megson believes up to 13 clubs are still involved in the Premier League relegation battle.
The Trotters are currently 11th in the table but Megson believes even clubs as high as eighth-placed Manchester City are still not yet guaranteed to be playing top-flight football next season.
Lower down, just five points separate the eight teams above the drop zone in a congested lower half of the table.
"Blackburn's result last night (winning 2-1 at Fulham) is a great result for them. But it didn't just take them out of the bottom three, it created an even bigger relegation battle," said Megson.
"There are more teams now involved in it. The last club in the bottom three is now on 28 points so it has got a little bit closer and dragged one or two others into it.
"I think everybody is in it apart from the top six or seven."
Speaking about his own side's survival chances, Megson added: "We're in a position of strength if we can use the position that we are in and keep getting one or two results and get ourselves out of this, hopefully sooner rather than later.
"Hopefully that will strengthen our position in terms of staying up and if results did go well for us and we creep up the table, then great."
