Chelsea can end a difficult week, which saw manager Liam Rosenior dismissed, by reaching the FA Cup final.
Hato told chelseafc.com: "I’m very excited. It’s something you dream of, and it's a dream coming true,’ said the Dutchman on the prospect of representing the Blues at Wembley.
"Of course, it gives us a chance to win a prize this season. I think I’ve played every game this season in the FA Cup, so it was a bit of a road, but we're finally at Wembley. We know how important it is for us to win this competition, so I'm very excited.
"It would mean a lot. I played at Ajax before, but I never won a trophy there. So this could give me the chance to win the first trophy in my professional career – it would mean a lot for me.
"I knew when I came to Chelsea that it is a club that plays for prizes. Now we have a chance to play the semi-final, and hopefully the final as well in the FA Cup. So I'm very excited and really looking forward to it."
