(Reuters) - Manager Manuel Pellegrini left reporters in suspense on Friday when he refused to reveal who he would select in goal for Manchester City's Premier League home clash with Swansea on Sunday. Taking the initiative at the start of his weekly news briefing, Pellegrini praised England international Joe Hart's performance in City's midweek Champions League victory over Viktoria Plzen of the Czech Republic. "Yes I have a lot to think about, but that is my job," Pellegrini responded. The Chilean manager added that Serbian defender Matija Nastasic would be out for three weeks with a calf injury, suffered during City's 6-0 triumph against Tottenham Hotspur last Sunday.
