Of course they can, any team that makes it to a final has a chance of winning the trophy and if they were not strong enough, there's no way they could have progressed as far as the final. Chelsea fans will be watching the Liverpool v Fulham game today with interest, Liverpool hold a 2-1 advantage coming into this game, but this second leg is at the Craven Cottage, so it is going to be interesting and i think Fulham have a small chance. Chelsea would remember their recent defeats in cup finals against Liverpool, so they would either hope to meet them in the final for revenge or they might prefer a London derby final with Fulham.
