Manchester City will decide in the next month whether to extend the contracts of a group of big-name players whose current deals expire in 2014.
Gareth Barry, Carlos Tevez and Joleon Lescott are all out of contract next year and, if City do not offer them extended deals, they may be tempted to sell to ensure they do not leave on free transfers.
Manager Roberto Mancini, who has previously stated that he is keen to keep Tevez beyond next season, praised Barry, who has been an automatic choice in the centre of City's midfield.
He said: "I think we have three or four players in this situation. We will decide this in the next month but these players are important players for us.
"I am very happy with Gareth because Gareth is a good guy and a serious professional player. He is a really serious like a man.
"Tevez, Barry and Lescott were all big-money acquisitions in the summer of 2009, when they signed lucrative contracts in former manager Mark Hughes' reign.
Tevez, thought to have cost up to £47 million, has scored 73 goals in 139 games since leaving Manchester United while Lescott, a £22 million buy from Everton, has made 129 appearances in defence and Barry has played 167 times for City.
City have arranged a post-season tour of the United States and will face Chelsea in first St Louis and then New York in May and Mancini expects Tevez to be part of their squad, despite his conviction for driving while disqualified and without insurance and the reluctance of American immigration officials to let some people with criminal records into the country.
The forward was sentenced to 250 hours of community service, which he has started this week, and Mancini joked that Tevez could sweep the streets of New York as part of his punishment.
"Could be, why not?" he said. "It is better in New York."
Mancini said he is normally opposed to playing friendlies abroad after the season has ended but has made an exception for their trip to the United States.
"The club decide this," he added. "We accept this. We don't have a problem but usually I don't like this because when we finish the season it is finished. But it is not for me. We go to New York because it is a holiday - it is true. We go to play two games for the club because it is important."
