SAM Allardyce is a manager in the results business - and any Wanderers fans expecting him to change could face a long wait.

In a week where the 4-5-1 formation has come under intense scrutiny from all angles, the founding father of the system found out some of its limitations as Wanderers struggled to break down a resilient Blackburn side.

The Wanderers boss has been employing the controversial tactic since the club entered the top flight six years ago, and as the rest of the Premiership follow suit, Allardyce admits his job is becoming tougher.

He said: "It's making it difficult to tough it out now, but if it is good enough for Manchester United and good enough for Chelsea, we've been doing it for six years now, so it is good enough for us.

"Blackburn showed us respect because of the way we have played over the last year. Everything we tried to do, Blackburn closed us down.

"Nobody came out with a flash of brilliance. Jay Jay, Campo, Dioufy or Stelios could have just turned the game in our favour.

"The game was crying out for a goal and because it never came it became a hugely scrappy affair."

As the teams trudged off from the Reebok pitch, a buzz of discontent resonated around the stadium following what had been a poor spectacle. But as Allardyce pointed out, his side had moved into fifth place in the Premiership above Tottenham and earned another clean sheet.

"There wasn't much entertainment today, but necessity overrules entertainment, sadly," he said.

"Necessity is money. Everything revolves around money in the Premiership.

"Money only comes with results and you can only keep your job if you keep points on the board. If you lose 5-4 and play attractive football, you get booed in the end and you get sacked.

"Individually we know we can do better. But to give them credit, Blackburn Rovers as a unit stopped us playing. We wouldn't have got booed if we won 5-4, but we wouldn't have got booed if we won 1-0 either."
