Manchester City boss Roberto Mancini has admitted he is struggling to instil a winning mentality into every member of his Eastlands squad.
City host champions and Premier League leaders Chelsea on Saturday lunchtime in what will prove a yardstick as to how far they have come under Mancini.
The Italian spent around £120million during another busy summer of transfer business at the ambitious club, but Mancini is still not completely satisfied with the players he has at his disposal.
"There are players whose only target is their day off and that is a big problem," he told the Daily Mail.
"You must replace them with those whose target is the win against Chelsea, then against Arsenal, then against Manchester United, who will work every day for this. Yes, there is still the day off, but you must never lose your focus even then.
"Before, at this club, there were players whose targets were wrong, but that mentality is changing.
"Those whose targets were wrong are the ones who have left. I tell them there is no day off now.
"The top players will play Saturday in the Premier League, Tuesday in the Champions League, Saturday in the Premier League. It is impossible to rest.
"Yes, there is one day you can use to recover, to have a massage, but your head must always be on the pitch and on your job."
