Authenticity (2.5/5): Chelsea targeting Costa move
Costa has already been linked with Man City and Man United ahead of the summer transfer window, and it now appears that another Premier League club have entered the race for his services.
According to TEAMtalk, Chelsea are also considering Costa as a possible target for the upcoming transfer window. The report claims that the Blues are keeping a close eye on his performances at Porto.
Value (3.5/5): Costa has Porto release clause
Costa is under contract until the summer of 2027, although there is said to be a €75m (£64.5m) release clause in his deal.
However, there is a belief that Porto could be open to negotiating a fee below the £64.5m mark.
Suitability (4/5): Highly-rated goalkeeper
Costa has recorded 15 clean sheets in 30 league appearances this season – three more than any other goalkeeper in the Primeira Liga.
The 25-year-old is Porto's captain and the number one goalkeeper for Portugal, demonstrating the regard he is held in by both club and country.
Upgrade? (4/5): Sanchez replacement
Costa would surely be a better option than either Robert Sanchez or Filip Jorgensen, who have both struggled to convince in the Chelsea goal this season.
The Porto goalkeeper would bring plenty of experience to Stamford Bridge, having featured in 195 competitive matches for the Portuguese giants.
Logic (3/5): Plenty of options
Costa could have a number of options on the table if it becomes clear that he is open to leaving Porto this summer. A key factor in his decision could be whether any of his potential suitors will be able to offer Champions League football.
Chelsea and Man City are both aiming to secure a top-five finish in the Premier League, while Man United are hoping to qualify for the Champions League by winning the Europa League.
Whisper+ verdict: 17/25
Costa would be a strong option to bolster Enzo Maresca's goalkeeper options, but they will have their work cut out to win the race for his signature.
