Manuel Pellegrini is not worrying about the prospect of losing Sergio Aguero in the summer and has also insisted it is difficult for Manchester City to sign English players.
Aguero has averaged better than a goal every two appearances for City since his 2011 arrival from Atletico Madrid, but he has been linked with a summer move to the club's UEFA Champions League opponents Barcelona.
City head to the Nou Camp for the second leg of their last-16 tie on Wednesday, trailing 2-0 from the first meeting, but Pellegrini is not concerned that Aguero wants to go to Barcelona permanently.
"I don't think the idea of Sergio is to leave Manchester City," Pellegrini is quoted in the Sunday Mirror.
"Sergio is very happy here. You never know what can happen in the future, but he is a very important player here.
"Big clubs do not sell their best players and I don't think Sergio will be going anywhere."
Meanwhile, Pellegrini is also not concerned by the lack of English players in his squad amid suggestions the Capital One Cup winners will struggle to meet the home-grown criteria next season.
Joleon Lescott's contract expires at the end of the season, while Micah Richards, Jack Rodwell and James Milner have all been linked with summer moves.
"I don't think anyone at the club is worrying about where the players are from," said the Chilean.
"It's not a thing of nationality. It's a thing of the best team. A lot of teams are like that. Maybe sometimes teams in Spain don't play with Spanish players.
"It's very difficult to have important English players in every team. They are very expensive and you don't have too many English players.
"All the important teams have English players in their side but, if you want to buy an English player, it is difficult.
"We have five English players and three of them - Joe Hart, Joleon Lescott and James Milner are very important. The other two - Micah Richards and Jack Rodwell - have had an unlucky season because they've had a lot of injuries.
"Foreign players are very important and English players are exactly the same. Technically, physically and tactically, they are the same. There are English players in all the big teams here.
"But it is not easy to bring another English player to Manchester City because who will sell?
"I don't think Liverpool would sell their four or five important English players, the same for Chelsea or Manchester United and every team. It's the same for us. If someone came here to buy Joe Hart, City would not sell him.
"We're in England. I know it is important for English football to have English players in every team. But first we must first finish this season and we will see what happens.
"We know we have to have a certain amount of English players, so we'll see the way we do the list next year.
"Of course, we are always thinking about next season, but we don't have to have any decisions to make at this moment.
"Richards, Rodwell, Milner and Hart all have contracts with the club. Only Lescott finishes his contract - maybe he will not continue here."
