At the start of this season, Bosnian international Asmir Begovic signed for his former club AFC Bournemouth after two seasons with Chelsea.

During his time at Stamford Bridge, the 30-year-old made 33 appearances and even helped The Blues lift their fifth English Premier League title.

His time in South West London was spent primarily sat on the substitutes bench as Thibaut Courtois’ understudy.

Begovic signed for Chelsea for £8 million from fellow top-flight club Stoke City to replace long-standing club legend Petr Cech, who had departed for London rivals Arsenal.

At the time, Chelsea fans were apprehensive on his arrival; whilst he was in great form for Stoke City, Blues supporters also felt that a goalkeeper of his calibre might have been too good to be regularly sat on the bench every week. Fortunately for the Bosnian, Begovic received several first team opportunities at the start of his Chelsea career, following suspension and injury for Courtois.

When Chelsea’s Belgian stopper returned, Begovic reverted to a role on the bench and remained there for the next 18 months, albeit other than a few cup ties.

His departure left The Blues short in terms of senior goalkeepers, with Courtois and Portuguese veteran Eduardo as their only options. To strengthen their squad, Chelsea signed free agent Willy Caballero, who had been released by Manchester City after spending three seasons at the Etihad Stadium.

Until earlier this month, Caballero had only featured for Antonio Conte’s men in the EFL Cup, however, an ankle injury sustained by Courtois has left Caballero as first choice in recent weeks.

Begovic is set to come against his former club on Wednesday evening at Stamford Bridge and with Courtois not a certainty to start, Caballero could be set to make his fifth consecutive start in a Chelsea shirt against AFC Bournemouth.

Here is how Courtois’ deputies of past and present have compared so far this season.

AFC Bournemouth’s keeper has featured in all 24 of The Cherries’ league games this campaign but he did not feature during any of their six cup ties this term. Meanwhile, Caballero has played just eight times for The Blues, with his sole league appearance coming during the 4-0 victory over Brighton and Hove Albion a week-and-a-half ago.

Despite playing 16 more games this season, Begovic has recorded just one clean sheet more than his Argentinian replacement.

On average, Caballero has only conceded 0.75 goals a game, whilst Begovic concedes twice as often, with a rate of 1.5 goals let in per outing.

With these two Chelsea goalkeepers of past and present possibly set to do battle on Wednesday, can either guide their side to three points in SW6?
