"Aguero is getting better. The good news is that he's on the pitch with us. We'll see if he'll be back soon," Guardiola said in a news conference. "I'll do 700 more then retire. I never expected it.

"Fulham are an encouraging team. I enjoy watching them for the way they play... they made an incredible result winning at Leicester. We know the opponent we're going to face tomorrow."
