Sergio Aguero, David Silva overcome virus, available for Man City opener

MANCHESTER -- Sergio Aguero and David Silva will be in contention for Manchester City's Premier League opener after overcoming a virus.

The striker missed the ceremony where he was crowned City's player of the year for the 2014-15 campaign after he, Silva and Samir Nasri were sent home from training on Wednesday because they had a stomach bug.

But all three could face West Bromwich Albion at the Hawthorns on Monday.

"Aguero, Silva and Nasri: they are working hard," Pellegrini said in a news conference.

But Pellegrini faces a decision whether to involve Aguero, Pablo Zabaleta, Martin Demichelis and Fernandinho, who were granted time off after the Copa America and have not featured in City's preseason games.

City will definitely be without left-back Gael Clichy and new signing Fabian Delph, who suffered a hamstring injury 18 minutes into his first game for the club, the 4-1 defeat to Real Madrid in Australia.

"The only players that will not be fit for Monday are Clichy, who has a problem in his ankle in the last week and I don't think he will be 100 percent fit to be in the squad list on Monday and Fabian Delph," Pellegrini said.

"He has his hamstring injury in the preseason. All the other players I think will be fit. Aguero, Silva, Nasri they are working hard. Aguero is 100 percent, Silva also. Nasri is returning from his illness."

"Maybe the South American players are not 100 percent to start the season but they are working very hard and very well."

Raheem Sterling is set to make his competitive debut after becoming City's record signing when he joined for £49 million from Liverpool.

Pellegrini is confident the winger will prove more prolific for City than for his former club and feels he will slot into a different side with few problems.

"I have a lot of trust you will see Raheem scoring a lot more goals than he scored for Liverpool," he said. "It is easy for good players to settle in a good team. I think we are going to have a very successful player this year."
