Silva (hamstring) is a big doubt for Sunday's clash against Liverpool, coach Pep Guardiola said in a press conference, according to BeanymanSports. "Yesterday he said to me 'I feel quite good. I want to try'. But I don't know. It's in a position less dangerous than the hamstring, another type of muscle in the hamstring position. But we'll see in the next days. 'Could be OK' is not the words. He's an incredible doubt. He will try, I think so, knowing him, he will try. But right now, I don't know."
