The pair could come face to face with one another when Dúbravka’s Slovakia take on Dummett and Wales at the Cardiff City Stadium a week on Sunday.
Slovakia kick off their Euro 2020 qualifying campaign at home to Hungary next Thursday, a day after Wales welcome Trinidad & Tobago to Wrexham’s Racecourse Ground for a friendly.
The two sides then lock horns in the Welsh capital 72 hours later, with both looking to qualify for a second consecutive European Championship. Croatia and Azerbaijan join the pair, as well as Hungary, in Group E, with just the top two progressing to next summer’s pan-European tournament.
