Peterborough boss Darren Ferguson is adamant his side will need more than 50 points to avoid npower Championship relegation after further boosting their tally with a 1-0 victory at Blackpool.

Midfielder Kane Ferdinand headed home the only goal of the game and his first for Peterborough on the stroke of half-time as Ferguson's troops extended their unbeaten run to five.

Posh still sit third from bottom but are just a point shy of Sheffield Wednesday, who lost 2-0 to leaders Cardiff, while Barnsley are another point away. And, with eight games of the season left, Peterborough boss Ferguson believes Posh are going to need more than a point a game.

"I thought my players were magnificent. It's a big three points. In the first half I thought Blackpool were the dominant team," said Ferguson.

"We were a little bit lucky, Bobby Olejnik made two or three top saves and we scored with only our real clear-cut chance of the half. But in the second half we were far better.

"It gets us to 42 points. No-one can even start to predict how many you need to stay in the league but no way is 50 going to be enough.

"But we are on a good run, we are unbeaten in five. Before the game, I showed the players the league after seven games and I showed them the league now. For us to be in the position we are in, they deserve credit for that. We threw away 21 points at the start of the season. But we are catching up. It's one of those seasons."

Meanwhile, Blackpool boss Paul Ince believes the loss of midfielder Barry Ferguson not only affected the match but could impact on their own battle for Championship survival.

The 35-year-old sustained a head injury in the first half, requiring eight minutes of treatment on the pitch, and Ince said: "Losing Barry Ferguson was a big loss to us. I said last week he was pivotal to the way we play. We lost him when we were in the ascendancy and then it stopped the play of the game when he was down for eight or so minutes.

"So that was a big blow and then to concede the goal in the 45th minute was really disappointing. We started really well; we had three or four good chances. We looked like the team that was going to score. The performance wasn't bad but we have got to understand that we are in a fight now."
