Alex Ferguson has spoken to Wayne Rooney and is convinced the England camp is racked with tension.
Englandâ€™s dismal start to the World Cup means they must beat Slovenia tomorrow to make the knockout stages.
And Manchester United boss Fergie said: â€œSometimes the expectation can be debilitating.
â€œI had that feeling. I spoke to Wayne Rooney and just said, â€˜relax and enjoy it.â€™
â€œI just sensed there was a tension in and around the camp from what I was hearing.
â€œI didnâ€™t watch the Algeria game, I was out with friends, but I just get a feeling that the expectation is affecting the England team.â€
Fridayâ€™s dismal 0-0 draw with the African side ended with United hitman Rooney slating fans who booed.
Roo also struggled to impose himself in the 1-1 stalemate with the United States.
But while England have floundered, Fergie believes the whole tournament has failed to spark.
He said: â€œItâ€™s been a disappointing World Cup, but I had a feeling it would be.
â€œI have been disappointed with the quality levels, I havenâ€™t been impressed at all.
â€œThe season we have in Europe, particularly in England, is tough.
â€œThe players met up about 3-4 days after the season finished and they have been together for most of that time, after a long, hard season.
â€œItâ€™s a real task to ask players to perform at the best level they can achieve after the season in England.â€
Slovenia skipper Robert Koren says his boys will put England out of the tournament by winning tomorrowâ€™s Group C showdown in Port Elizabeth.
Koren, recently dumped by West Brom, said: â€œWeâ€™ve been playing some very good football for two years.
â€œIâ€™m sure England will be up for this game because they have to be. Despite that, I think 2-0 to Slovenia.â€
