"I still need to work hard for another week and if not this week, then maybe next, I hope to start training with the rest of the lads and so my target is Liverpool."

Aguero scored a club record five goals in a 6-1 win over Newcastle United in his last City appearance.
"I'll take things slowly and not rush into anything, but I'm not far away," he said.
