United needs time to learn my methods - van Gaal

New Manchester United manager Louis van Gaal has warned fans not to expect instant success, saying it will take three months for his players to get used to his style and methods.

The Dutchman, brought in following the sacking of David Moyes less than 10 months after taking the job at Old Trafford, is introducing a new 3-4-1-2 formation and increasing the technical demands on his players.

United, which finished outside the European places in seventh last season, plays Swansea City, Sunderland and Burnley in its first three Premier League matches but despite a relatively comfortable start, van Gaal warned against immediate success.
