Kepa Arrizabalaga's Chelsea career could be over. 

The Spanish goalkeeper has failed to impress since arriving at Stamford Bridge in 2018 and may have put the last nail in his own coffin on Sunday.

With the Blues 1-0 down at home to Liverpool, Kepa was far too casual in clearing the ball from his own six-yard box and gifted Sadio Mane a second goal. 

It was a mistake you're more likely to see in Sunday League, rather than the Premier League. It looked like the mistake of a beaten man. 

Maybe even Kepa himself knows his time as Chelsea's number one is up. Rennes goalkeeper Edouard Mendy is expected to arrive this week to relieve him from his duties. 

If the Spaniard really is kicked to the bench, he will go down as one of the club's biggest-ever flops, considering he cost £71 million just two years ago. 

But who else would join him in a 'Chelsea flop XI'? Let's check it out below. 

Kepa will be replaced by Chelsea

Goalkeeper - Kepa Arrizabalaga 

Kepa really does have more low-lights than highlights in a Chelsea shirt. 

The most famous, perhaps, was refusing to be substituted in the League Cup final by Maurizio Sarri before losing the penalty shootout.  

More recently, his stats have put him amongst the worst goalkeepers in Europe and that mistake against Liverpool could be the last time he's between the sticks.

Kepa's career is over

Right-back - Khalid Boulahrouz 

Chelsea fans might be thinking 'who?' but Boulahrouz was a Blues player for two years between 2006 and 2008. 

Despite being a full back, he was handed the No.9 shirt by Jose Mourinho, who hailed the defenders ability to play centrally or out wide.

Sadly, he played neither position particularly well and after failing to hold down a starting spot, was sent on loan to Sevilla before moving to Stuttgart on a permanent deal.  

Boulahrouz played for two seasons

Centre-back: Papy Djilobodji

Chelsea may have only spent £3 million on Djilobodji in 2015 - but he's arguably not even been worth that.

The defender made just one League Cup appearance for the club before being sent out on loan to Werder Bremen. 

Less than 12 months later, he was sold to Sunderland and lasted just one more season in England, before moving back to France. 

Djilobodji made no impact at Chelsea

Centre-back: Tal Ben-Haim

The Blues signed Ben-Haim as backup to John Terry and Ricardo Carvalho in 2007, but even in a bit-part role, he struggled. 

The Israeli was given very few minutes and played just 13 times for the Blues before being shipped off to Manchester City.

It was there, that he was equally disappointing. 

Ben-Haim was a very forgettable player

Left-back: Baba Rahman

Like Djilobodji, Rahman was signed by Chelsea in 2015. 

And, like Djilobodji, he struggled. The Ghanaian has featured just 23 times in six seasons at Stamford Bridge, but incredibly, is still on the club's books.

He's had loan spells with Schalke, Reims and Mallorca, but the Blues are still paying his wage.

Rahman is still on Chelsea's books

Midfielder: Tiemoue Bakayoko

Bakayoko cost Chelsea £40m in 2017, but he's arguably been worth less than £4m in a blue shirt. 

In 46 games, he scored just three goals and provided three assists for the club. All those came in his first season before the Frenchman was shipped out on loan to AC Milan and Monaco.

It's said PSG are interested in signing him for £32m this summer... for some reason. 

Bakayoko could leave Chelsea

Midfielder: Danny Drinkwater

Drinkwater was another 2017 buy and he's another 2017 waste of money. 

The midfielder, who cost £35m, has made just 23 appearances in all competitions. He failed to nail down a spot in the Chelsea team and has since played on loan at Burnley and Aston Villa.

The less said about his spells there - and his off-field issues - the better. 

Drinkwater's Chelsea career was poor

Midfielder: Steve Sidwell 

It really is shocking that Sidwell got anywhere near Chelsea's side. 

Mourinho signed the midfielder after an impressive spell at Reading and strangely, handed him the no.9 shirt... where have we heard that before?

Behind the likes of Frank Lampard, Michael Ballack and Michael Essien, Sidwell failed to establish himself at Stamford Bridge and left after making just 15 appearances. 

Sidwell shouldn't have been a Chelsea player

Forward: Radamel Falcao 

Falcao was once one of Europe's top strikers... but by the time he ended up at Chelsea, he was far from that. 

The South American arrived on loan in 2015 and made 14 appearances over the course of the season. 

He scored just one Premier League goal and returned to Monaco at the end of the season. Rather surprisingly, he revived his career in France, scoring 70 goals in the following three years. 

Falcao was forgettable

Forward: Fernando Torres

Arguably, it's a little harsh to put Torres in this XI. He scored 45 goals in 172 games and won the FA Cup, Europa League and Champions League as a blue. 

But it's the Spaniard's £50 million, British-record transfer fee that makes him a bit of a flop.

In the eyes of almost all supporters, Torres never lived up to that price tag before being sold back to boyhood club Atletico Madrid in 2016. 

Torres struggled at Chelsea

Forward: Alexandre Pato

Like Falcao, it's crazy to think Pato ever played for Chelsea. But he did, for six months on loan in 2016. 

The Brazilian actually scored on his debut, but that's as good as it got. We should also mention that due to injury, that debut came three months after he joined. 

Pato played just twice for Chelsea and the club opted against making his loan deal permanent.

Pato was a Chelsea player

Well, there are a few terrible deals in there... for every Didier Drogba, Chelsea have had a Falcao. 

But arguably, none have been as disappointing as Kepa.
