Manchester City boss Pep Guardiola feels his squad is lacking numbers after victory over Aston Villa.
Guardiola was forced to play Bernardo Silva at the back for the 3-1 win.
He said, "We have just 18, 19 players. Our depth is so so small, maybe the smallest one in the Premier League by far. It's important that we don't have injuries but we have an incredible methodology for training to manage the fatigue and avoid injuries. We have incredible doctors and physios and everyone. I fight for that for many years.
On facing Arsenal and potentially go on top, Guardiola added: "Arsenal have a game in hand. We will see after all the games when the Premier League is finished. But we are going to London to try and get a win. When one team has made 50 points in the first leg it is because they are very good. we closed the gap today because the performance from the team was really really good.
"Supporters were really good today. I know they know our team has goals. In general it was really really good."
