Blake is convinced they can turn things around on their visit to the south coast.
He said: "This league brings pressure and we've got to deal with that. No-one expects us to stay up, but we're not showing at home that we're under pressure.
"We're fully focused on what we've got to do. We've got a big game against Portsmouth on Saturday but it's a game we can definitely win. This squad of players is about character.
"We've been knocked every week but we've beaten good teams at home and we've got a point at Manchester City. People have been saying, 'It will stop, they're not good enough' but I don't think that.
"We went 5-0 down against West Ham and scored three goals.
"We will cause teams problems and I think as a group of players if we do that that's better than sitting back."
