Manchester City boss Manuel Pellegrini says he took off Yaya Toure at half-time against Bournemouth because the midfielder was not fit enough to play the full 90 minutes.
The Citizens eased past the Cherries to keep the first place in the English Premier League.
The Chilean was also delighted with striker Raheem Sterling who claimed his first hat-trick for the club.
"I think it was important for Raheem to score three goals," Pellegrini said after the win.
"He must improve his finishing – he did that today, he's young and will continue to get better.
"I don't think he's a striker like Kun [Aguero] or Bony but this year, and I said it when he arrived, I am sure he will score more goals than he did in another season at Liverpool.
"[Yaya Toure?] He just played 45 minutes in the Champions League before he got in an injury.
"In the first ten days of the international break he did nothing so I thought 45 minutes was enough.
"It was not an important injury but one which prevented him from playing games.
"We start thinking about Sevilla tomorrow – we must focus our mind on each game. Bournemouth are not an easy team."
