Blues boss Phil Brown is preparing for a ‘massive’ week for his side, which starts with a trip to Fratton Park on Saturday.
Blues face a Portsmouth side who picked up three vital points away to Blackpool last weekend, after losing their previous three Sky Bet League One games.
And ahead playing three games in a week, Brown insists it’s an important trio of games ahead.
“It’s coming into our moment, this part of the season. If you look at the last five games, we’ve won three of them, drawn one and lost one, and the game we lost we scored a mystery goal.
“Simon Cox put the ball in the back of the net at Yeovil, it was denied by a linesman and in hindsight we’ve had information from the PGMOL that it was the wrong decision, it should have been given, and we could still be in the FA Cup.
“More importantly we didn’t lose the game in my opinion. We’ve conceded two goals in those five games and one was a penalty.
“There’s lots to admire and like about the performances of late, but more importantly the three clean sheets, and that’s something we have to go into Fratton Park on Saturday.
“They are capable of scoring goals, but so are we.
“We will be bouyed by nearly 1,500 supporters from Southend United going so we have to put a big performance in. This is one of the big games.
“This could be a turning point of the season and as far as I’m concerned it’s a massive week with two big away games and then back to Roots Hall against Oxford United.
“All those teams are in and around us and if we want to steal a charge on them three teams then we have to win games.
“We need a points total that will keep us in the pack at the end of this week coming into the Oldham game.”
A rare Saturday off last weekend allowed Brown to travel up to Blackpool to take in Portsmouth’s 3-2 win.
Brett Pitman, who scored two in that win, is the league’s second-highest goalscorer, with eight of his 11 goals coming at Fratton Park.
And Brown took a lot away from the scouting mission.
“I very rarely get the opportunity to watch the opposition the game beforehand but with us having the weekend off I went up to Blackpool to watch Portsmouth, and I got a hell of a lot from it.
“The system that they play, the personnel, the mentality of the group going into a game having lost four on the bounce, the travelling support, there was a lot to like about their performance.
“I learned a lot about the way they play, the style of football, and that for me is a rarity during the course of a season, through circumstances like Oldham having four international footballers.
“Certain things play into your hands and give you a bit of an advantage and other things don’t, but it was a worthwhile venture going up to Blackpool to see Portsmouth. But we’ve had a week on the training ground, and that’s the other side of it.”
