Manchester City striker Sergio Aguero is in contention for Sunday's Capital One Cup final with Sunderland at Wembley. City's top scorer has missed the last five games with a hamstring injury but returned to training earlier this week. The Argentina striker has scored 26 goals this season but limped off during the 5-1 win at Tottenham on 29 January. City manager Manuel Pellegrini refused to confirm whether Aguero would start against Sunderland but he is delighted to welcome him back into the squad.
