Either Fulham or Brentford will be promoted to the 2020-21 English Premier League after the Cottagers secured a spot in the play-offs decider despite a 2-1 defeat to Cardiff City in their second leg.
Curtis Nelson gave Cardiff an eighth minute lead but Fulham levelled a minute later through Neeskens Kebano.
However, Lee Tomlin put City ahead again early in the second half, ensuring a tense finale with one more Cardiff strike enough to go through on away goals, but Fulham held on to secure their spot in next week’s final.
“We’ve got ourselves to the Final, an incredible achievement in terms of a long, drawn out season,” Parker said.
“The goal was to get to the Final and we’ve done that. The performance tonight was tough, Cardiff made it very difficult for us.”
Fulham have been in the top flight in recent years, only last relegated in 2018-19 under Parker, while Brentford have never been in the Premier League.
“There was a massive prize on offer, the Final, it was a prize that we all wanted because we want that chance to try and get into the big league,” Parker said.
Parker was delighted his side did what they needed to do, to reach the final despite it being uncomfortable at times.
“There’s always points in football matches which are nothing to do with tactics or technique, its to do with a mindset, an understanding of the moment, and that was a prime example tonight,” he said.
“In the first half it wasn’t like that. They scored, but we had our quality and technique about us, and our structure and control got us through that half.
“The second half was totally different, it was a case of you’ve got to do what you’ve got to do to win a football match.
“You do what you have to do to get through this game and get to a Final. And we did that.”
