Sunderland manager Paolo Di Canio has cancelled his players' holiday plans as he looks to make sweeping changes at the club following their escape from Barclays Premier League relegation.

Although owner Ellis Short rang his head coach at midnight on Tuesday in the wake of Wigan's defeat at Arsenal – `he was singing at me he was so happy, it was amazing' – Di Canio was in no mood to celebrate.

The Sunderland boss has already started to make plans for next season and warned players heading to Tottenham on Sunday that they can expect four weeks, the minimum amount of time off for their summer holidays.

He has already ordered his players back to the training ground on Monday morning even if they have booked flights.

'If anybody has booked a holiday for Monday, they are going to lose some money,' he said.

'Why would they book a holiday on Monday? Why would they book a holiday before April 1st? They are not being serious, they have to ask me.

'If they did it before it is wrong and if somebody gave them a chance to organise a holiday in January or February it is wrong. I will see what happens on Sunday, then we will come back together, and I will tell them when their holidays start.'

Di Canio also revealed he had handed out a number of fines in the last week, including to players who had failed to attend the weekly signing session.

He added: 'It is seven steps to climb, 20 items to sign for children or supporters and it is important for them, but people forget. It is in the contract that they must, it is crucial to the club.

'Now they are fined because you have to start from somewhere or we're never going to change. It is small things, but many small things become a big problem. We have to respect the rules or we are never going to change.

'Everything means the mentality, we can't change everything. It doesn't mean we won't keep many players, but we will change some. That can wait until after Sunday.'
