This, according to The Sun:
Fergie is taking a new hardline approach this summer in a bid to reclaim the Premiership from Chelsea next season.
Nothing will make Fergie deviate from his plan to overthrow Jose Mourinho’s men — and that is the message the Scot will be booming out to his squad in a fortnight’s time.
A number of players are unhappy at having to return on June 27 — earlier than any of their opponents.
Players have had to cancel holidays and believe a break of only a month is not enough.
But Fergie said: "Chelsea turned last season into a sprint from start to finish. I’m determined that next season we hit the ground running."
For internationals like Roy Keane, the summer break has proved even shorter.
