Moses (above) is aware Chelsea will be huge underdogs to win the tie but believes they have the talent to pull off a shock result.
He said: “United are probably the toughest team [left in the competition].
“We’re looking forward to it. It’s not going to be an easy game, United have quality players and everyone will expect them to win.
“They have quality players from the back to the front. We just have to take each game as it comes — make sure we win games. That’s the most important thing. We can’t be talking about United playing us, we have to concentrate on ourselves.
“We have quality players here, they have good players, too. If we work together as a team, I can see us really going far and beating United but it’s not going to be easy.”
