With Liverpool FC already having Giorgi Mamardashvili in the picture, the renewed links to Diogo Costa raise an obvious question:
Why would they need both?
Mamardashvili complicates things
Mamardashvili isn’t just a backup option — he’s widely viewed as:
- A long-term No.1 candidate
- A high-upside goalkeeper
- Someone ready to step up
If Liverpool truly believe in him, then signing Costa would:
- Block his pathway
- Create unnecessary competition
- Tie up a huge amount of budget in one position
It likely depends on Alisson
Everything still comes back to Alisson Becker.
- If Alisson stays → Mamardashvili likely develops as No.2
- If Alisson leaves → Mamardashvili could step up
Only in a scenario where:
- Liverpool don’t fully trust Mamardashvili yet,
- or want instant elite replacement
…does a move for Costa really make sense.
Planning vs reality
At this stage, Liverpool are probably:
- Keeping options open
- Monitoring multiple elite goalkeepers
- Preparing for different outcomes
Costa being on the shortlist doesn’t mean he’s the priority — just that Liverpool are doing their homework.
Final thought
You can’t realistically have:
- Alisson
- Mamardashvili
- AND Diogo Costa
That’s three No.1-level goalkeepers — and no club operates like that.
So this isn’t about Liverpool wanting all of them.
It’s about uncertainty — and making sure they’re ready for whatever happens next.
