Chelsea had an expensive transfer window in January spending £323m on eight new additions to improve their Premier League season, however, it looks like the club are not finished in their pursuit of transforming the squad as a new potential target emerges.

What's the latest?

According to 90min, Chelsea are amongst a number of clubs scouting talented Porto goalkeeper Diogo Costa.

As per the report, it is claimed that the Blues are set to address their goalkeeper situation at Stamford Bridge in the summer with both Kepa Arrizabalaga and Edouard Mendy out of contract in 2025.

It is believed that Chelsea scouts are active across Europe with Costa one of the potential targets they are keeping an eye on alongside Manchester United who have also taken an interest in the young keeper.

Potter could ditch Kepa

There is no doubt that Todd Boehly is an ambitious owner who is dedicated to getting Chelsea back in contention for trophies as well as domination in both the Premier League and European football too.

The west Londoners are currently ninth in the top-flight table after a disappointing run of performance over their first 21 outings and are currently ten points adrift from a Champions League qualifying spot inside the top four.

Chelsea have the worst goal difference and have scored the fewest amount inside the top half of the table, missing out on crucial points and progression due to tight margins that have cost them dearly - losing by just one goal in a number of their games over the last few months against Manchester City, Fulham, Newcastle United and Arsenal.

Kepa - dubbed "error-prone" by broadcaster Bolarinwa Olajide - has been occupying the starting spot in goal for the Blues this season due to Mendy's injury issues and the controversial 'keeper has seen better days, conceding up to four goals per game on more than one occasion so far, having allowed in four against Man City in the FA Cup and another four against Brighton and Hove Albion in the Premier League back in October.

Indeed, the club's recruitment drive has been largely focused on improving the attacking threat over the most recent transfer window, but the signing of Costa in the summer could be a huge boost in their ability to see out games and improve next term.

The 23-year-old - who was dubbed an "enormous talent" by Sergio Conceicao - ranks in the top 2% of keepers in the next eight best competitive leagues for goals against and clean sheet percentage, as well as ranking in the top 12% for crosses stopped.

Not only that, over 19 league appearances this season the shot-stopper has made 36 saves, kept an impressive ten clean sheets and conceded only 11 goals so far, as well as winning 100% of his aerial duels per game, which is extremely eye-catching and could make him hugely valuable to Chelsea in the future.

With that being said, if the powers at Stamford Bridge are considering their options for a new gloveman this summer they should look no further than Costa. Indeed, he could provide the consistency and longevity needed to get Chelsea competing at the highest level once again.
