Manchester City boss Roberto Mancini says he always expected problems with the players over his training methods.
The complexities of keeping a Champions League squad happy on Europa League challenges has led to clashes with disaffected players, including Shay Given and Emmanuel Adebayor.
"I knew I would have problems with the training sessions because when I spoke to my friends David Platt and Gianluca Vialli they said English players only want to work in the morning," Mancini told the Daily Mail.
"But if you spend the week playing at three o'clock and eight o'clock it is not right to work only in the morning. Your body is not ready for it. So we change.
"I knew it would be difficult, but I tell the players the job is football and with football you live very well. Not just you, but your family and sometimes everybody you know; so you must be 100 per cent ready and this is how you get 100 per cent ready. It should not be impossible for you to compromise. And last year, I gave a little; not this year. This year we change."
