We had to wait until the 75th minute to make the breakthrough after young goalkeeper Bogdan produced an amazing string of saves.
And it turned out to be an unlikely hero as centre-half Ryan Nelsen headed home from Rafa van der Vaart’s corner for that all-important first goal.
Gareth Bale quickly made it 2-0 and any slight hope Bolton might have had of a comeback in added time after Kevin Davies’ late reply were dashed when Louis Saha hit a beauty for 3-1 with the final kick of the tie.
We will now meet Chelsea at Wembley on Sunday, April 15 for a place in the FA Cup Final against either Liverpool or Everton - the Blues booked a Merseyside derby in the other semi-final thanks a replay win at Sunderland.
“We dominated the game but couldn’t get that first goal,” reflected Harry.
“It took a long while to come but their goalkeeper was amazing. I’ve never seen a keeper make so many saves. It was one of the great goalkeeping performances.
“He made save after save, we hit the woodwork - we had an incredible amount of chances.
“I said at half-time that the goals had to come if we kept playing the way we played. They had to come.
“But the second half started and he continued making save after save. You do start to wonder if it’s going to be one of those nights but eventually the goals came.”
