It might just have been Albion’s worst ever night at the Amex.

Only play-off defeat to Wilfried Zaha and Crystal Palace competes for that dubious honour.

It was the hugely unpleasant night when home fans jeered their club’s manager as his team slipped to a 1-0 home defeat by Millwall.

They were scenes never seen before or since at the Seagulls’ home in Falmer.

It is four years ago TODAY since that 1-0 defeat left Sami Hyypia on the brink.

It was to be his last home game in charge.

Millwall’s second win in 16 games, secured by Lee Gregory’s 14th-minute goal, led to home fans turning on Hyypia.

Some in the North Stand chanted ‘We want Sami out’ and sang in praise of his predecessor Oscar Garcia.

Head of recruitment David Burke, whose days also turned out to be numbered, did not escape their wrath.

A banner unfurled in the North Stand during the first half read: “Sorry Sami time to go and take that Burke with you.”

The defeat, on a freezing Friday in Falmer, turned out to be a watershed moment in Albion’s history.

Hyypia remained a hugely dignified figure throughout but, four years ago tonight, his position appeared untenable.

He resigned after the next away game, a 1-1 draw at Wolves.

Nathan Jones steadied the ship as caretaker boss before Chris Hughton came in to well and truly turn things around.

Albion now sit mid-table in the Premier League, with 21 points from 16 games.

That’s three more points than they had from 21 Championship fixtures four years ago.

Defeat left Albion still in the drop zone, two points behind Rotherham having played one match more.

Albion’s bad run stretched to one win (1-0 at home to second-from-bottom Wigan) in 17 games.

Their team for this match included three current starters – Bruno, Lewis Dunk and Solly March, who played on the right wing.

David Stockdale was in goal with Greg Halford and Adam Chicksen completing the back four.

Jake Forster-Caskey and Gary Gardner filled deeper midfield roles in a 4-2-3-1 set-up.

João Teixeira played down the left and Elliott Bennett was at No.10 behind Darren Bent.

It was Halford’s full debut and he was one of five loanees in the starting 11.

Paddy McCourt and Adrian Colunga were sent on in an increasingly desperate second half and Christian Walton, Rohan Ince, Aaron Hughes, Danny Holla and Inigo Calderon remained unused on the bench.

None of that year’s seven summer signings made by, or moe probably for, Hyypia started the game.

To quote Fat Boy Slim, Albion life is full of “we’ve come a long, long way together” type landmarks in their current healthy state in the top flight.

Today, exactly four years on from the Amex’s most toxic night, is one of them.
