Emma Hayes said it best after Ann-Katrin Berger produced penalty shootout heroics to ensure our passage into last season's UEFA Champions League semi-finals: 'She is someone who thrives in the big moments.'

Berger, who today left Chelsea to join Gotham FC, proved herself a big-match player down the years – and never more so than in that famous shootout against Lyon at Stamford Bridge.

The German international also won nine major trophies during a glittering spell with the Blues and set consistently high standards in one of the most important positions on the pitch.

Her standout performances and key moments for the Blues will live long in the memory. We have picked out five of our favourites...

Man City (A) – February 2020

The first of our current WSL-winning spree came in the 2019/20 season. Given how the title was decided that season, it's fair to say Berger played a significant role in the Blues lifting the trophy.

It was first versus second heading into the game and then-leaders City opened up a 2-1 lead through Georgia Stanway in the 60th minute.

Magda Eriksson responded for the Blues but with minutes remaining, Caroline Weir was brought down in the box and City had a golden opportunity to re-establish their advantage and take a commanding position in the title race.

Instead, Berger produced a trademark penalty save, and moments later Chelsea went ahead as Beth England scored with a powerful drive.

In the blink of an eye, Chelsea had gone from letting the title potentially slip away to getting a hand on the trophy, thanks in huge part to Berger.

City were able to force an equaliser but the draw proved a vital result for Emma Hayes’s team as, after the international break that followed, the WSL season was halted due to the Covid-19 pandemic.

It meant the title would be decided on points per game and that meant unbeaten Chelsea – one point behind City but having played one game fewer – were crowned champions.

Had Berger not saved Stanway’s spot kick, the championship may very well have ended up with City.

March 2020: Chelsea 2-1 Arsenal

The best performance of Berger's Chelsea career arguably came in the Women's League Cup final. Old foes Arsenal were the opponents at the City Ground as the Blues aimed to win the competition for the first time.

England put the Blues ahead after eight minutes but Arsenal took control of the contest and peppered the Chelsea goal. Berger repelled almost everything that came her way.

Magnificent saves were made to deny Louise Quinn, Katie McCabe, Jordan Nobbs and Vivianne Miedema, but Berger was finally beaten five minutes from time as Leah Williamson poked home from close range after a corner.

Berger deserved to leave the City Ground with a winner's medal; her performance was undoubtedly the best of those on the pitch. And in the 90th minute, England netted her second to ensure the Blues lifted the trophy.

‘She [Berger] was unbelievable,’ Hayes reflected. ‘We talk about attacking being the most dominant feature of a match, but why don't Chelsea deserve to win the game based on an outstanding goalkeeping performance? It’s not often we have to defend like that.’

March 2021: Chelsea 2-0 Atletico Madrid

Champions League football often brought out the best in Berger – the first leg of our last-16 clash with Atletico in 2021 is a classic example.

On a misty night at Kingsmeadow, we were dealt a significant blow early on when Sophie Ingle was sent off for a professional foul on Rasheedat Ajibade after just 12 minutes.

Not only were Chelsea reduced to ten, but Ingle’s misstep had taken place inside the box, handing Atletico an early penalty. Berger came to the rescue

A perfectly-timed dive down to her right denied Deyna Castellanos. It was a save that re-energised the Blues and just before the hour mark Maren Mjelde dispatched a spot kick to put us ahead.

Fran Kirby added a second soon after and Chelsea had opened up a strong lead. However, with 12 minutes to play, a collision between Berger and Ludmila saw Atletico handed their second penalty of the evening.

Once again Berger stepped up and made her second save penalty save of the night and Chelsea would ultimately advance from the tie.

‘The first penalty save was crucial because it's a time when you might wonder how difficult the evening is going to be,’ Hayes would state.

March 2021: Chelsea 2-1 Wolfsburg

Chelsea went into the first leg of this Champions League quarter-final tie knowing the German outfit had ended three of their previous four European journeys. It was an opportunity to put that hoodoo to bed.

Berger certainly played her part in the Blues doing so. It was a backs-to-the-wall display from Hayes's side but Chelsea managed to establish a two-goal lead in the second half after Pernille Harder and Sam Kerr struck.

Berger made save after save in the Chelsea goal; the standout being a wonderful double stop from Fridolina Rolfo that almost defied logic.

Berger also claimed countless crosses and set pieces as Wolfsburg pushed forward in search of a route back into the game. They found one via a Dominique Janssen penalty, but even after requiring medical attention late in the game, Berger ensured we left with a 2-1 lead.

And when the Blues stormed to a 3-0 win in the return leg the next week, a place in the last four was ours.

March 2023: Chelsea 1-2 Lyon (4-3 on pens, 2-2 agg)

Another Champions League quarter-final resulted in another AKB masterclass.

What else can be said about a truly magical night at the Bridge? Lyon, for so long the standard bearers of Women’s European football, looked to be going through after Sara Dabritz drove home to give the French side an extra-time lead.

Defeat would have been extremely harsh on Berger, who had put in an outstanding display in the first leg to keep a clean sheet. Yet there were still plenty more twists to come on a dramatic night.

In the dying seconds, Lauren James was brought down by Vicki Becho. After a VAR review, a penalty was awarded. Maren Mjelde fired home in front of the Shed End and the tie would be settled on penalties.

What followed cemented Berger’s status at Chelsea. She made two stunning saves, one from Lindsey Horan and one from Wendie Renard, to seal our place in the semi-finals once again.

Wild celebrations around the Bridge followed as Berger sprinted to the corner flag in celebration with Chelsea teammates in hot pursuit.
