Portsmouth manager Paul Cook on BBC Solent Sport:

"The disappointment and the pain of losing to Plymouth in the play-offs, I can still remember it now, I can still see their lad scoring.

"To see Pompey fans celebrating like that today is something that will remain with us all for a long time.

"It is our moment now and I think we should all enjoy it."

Hamza Darby: Rowett's sacking & Zola's appointment was footballing suicide. Rowett must chuckle himself to sleep every night now.

Karl HIlls: I am absolutely over the moon that Zola has gone! Wrong man for the job! Time to fight for our survival with 3 to go #zolaout

Juppster: Zola - about time. He will go down as the worst manager in the club's history. 2 wins isn't good enough. 7th to 20th in a few months.

James Blayney: Zola's tenure as Birmingham City manager was a disaster from start to finish. Shame he didn't resign earlier as it may be too late.

Not too much to report from Pride Park but it has been all Derby in the second half in terms of possession.

Huddersfield, who have lost their last seven trips to Derby, look reasonably comfortable in defence without offering much of an attacking threat.

Here's what some of our BBC journalists make of the news that broke just before 18:00 BST - Gianfranco Zola's resignation as manager of Birmingham City...

Darren Bent is just unable to get in front of Martin Cranie as Derby make a brightish start to the second half. 

Of course, Rams boss Gary Rowett was sacked as Birmingham manager when they were just outside the play-offs and now the Blues are facing the prospect of relegation - a penny for his thoughts?

Simon Atkins: FINALLY. Zola should have walked/been sacked months ago. The rebuild starts here! 

Thomas Stirk: Zola took a team fighting for play-offs, to fighting for survival. Was never the right man to replace the harshly sacked Rowett.

Richard Mark Bradley: Brilliant for Brighton. Saw them come so close last season at the Riverside, I'm sure they'll be pleased to see us go the other way!

Former Chelsea and Italy forward Zola was controversially appointed in December by Birmingham's new Chinese owners.

Gary Rowett had been sacked with Blues seventh in the Championship and level on points with the team in sixth position.

It's been a steady decline since then, with Blues now firmly in a relegation battle with three games to play.

Plymouth captain Luke McCormick on BBC Radio Devon:

"It's overwhelming really, we've been trying to do this for certainly the last three years and even before that.

"The club's been through some real tough times and this is the other end of the scale.

"The fans on the pitch in front of me, they deserve it more than anything.

"The 35,000 who went to Wembley last season [when Plymouth lost the play-off final], they deserve this, this is for them."

• Brighton beat Wigan 2-1 and have been all but promoted to the Premier League. For them not to get automatic promotion, Brighton must lose their last three games and Huddersfield must win their final five, including the ongoing match at Derby, as well as affecting a 32-goal swing.
• Newcastle lost 3-1 at Ipswich to fall seven points behind leaders Brighton.
• Leeds lost 1-0 at home to Wolves and dropped out of the play-off places, as Reading, Sheffield Wednesday and Fulham all won.
• Blackburn drew with Bristol City but remain in the bottom three. Defeats for Nottingham Forest and Birmingham drag them closer to the relegation zone.

German striker Collin Quaner's third goal since moving to Huddersfield has them ahead at Pride Park in the best move of the game.

Derby have enjoyed a lot of the ball in that first half but have not really done much to break down a well organised defence. Matej Vydra had a half chance in injury-time from a quick free-kick.

Remember that mathematics are actually stopping official confirmation of Brighton's return to the Premier League.

That's because if Huddersfield win today, win the rest of their games, Brighton lose their remaining games and the Terriers score a bag load of goals, it could all change...

Peter Austin: Watched the result come in from Peru... Up the Seagulls... Flying the flag with pride in Peru! Time to move back to the UK! 

Andy Salamonczyk: Brighton this season have reminded me of watching Leicester get promoted in 2014. The sky's the limit..

Joel Upward: Pompey fan who still has tears flowing down their face after promotion, such a sweet moment for everyone involved in the club

We asked if you if you're a fan of a promoted side, what are you most looking forward to. Here's a cracker.

Jago: To hearing Gary say 'and now we head to the Amex' on Match of the Day...
