Manchester City midfielder David Silva says they must throw everything at the FA Cup.

Silva insists Manchester City's FA Cup quarter-final against Barnsley is vital now the league is virtually out of reach.

"The league is very difficult," Silva said. "But we can reach the Cup final, so we have to focus on this game.

"In England, smaller teams can get to the finals. On paper, Barnsley are a small team, but they are in the quarter-final because they deserve to be, so we will have to be very cautious."
