The North-West outfit are expected to secure second place in the table due to their six-point lead over Chelsea.
"I have been saying for weeks that this football club is obligated to win football matches," Sky Sports News quotes Platt as saying.
"If we can secure second place within the next two or three games that won't put any kind of slant on our last two games, at Reading and at home against Norwich. We want to win football matches, that is what the players want to do."
City, who will go up against Wigan Athletic in the FA Cup final next Saturday, relinquished the league title to Manchester United last week.
