If Chelsea manager Jose Mourinho knows who his primary shot-stopper is heading in to the club's debut test in the 2014-15 Premier League season on Monday, against Burnley, he is not giving anything away as, at a press conference earlier today, Friday, he refused to answer who the number one will be between veteran gloves-man Petr Cech and ambitious youngster Thibaut Courtois.
For the Portuguese coach, both goalkeepers are amongst the very elite in Europe and due to their excellence, they represent a dilemma that all top managers would love to have.
However, neither of them knows who will be first choice at Turf Moor, as Mourinho explained: "I don't tell you because they don't know. The keepers don't know and the team doesn't know.
"They will know all at the same time," he added.
"In my opinion, with all the respect, they are two fantastic goalkeepers. I think Chelsea has two of the three best keepers in the world [the other, presumably, World Cup winner Manuel Neuer] and this is something unique.
"So is it a problem for me? A great problem! A great problem because they are both fantastic goalkeepers - even [third choice Mark] Schwarzer. Obviously he is of a different age and different level but he is also very good. So to have Petr and Courtois is a good problem.
"It is a problem every manager wants to have."
Courtois has flourished in the past three seasons having helped Atletico Madrid break the duopoly that Barcelona and Real Madrid asserted over the rest of La Liga as he returns to West London as a league champion. He is also in danger of losing his international place with Belgium should he be starved of first-team football.
Cech, meanwhile, is accomplished and established at the elite-level and would walk into many first-teams around the continent should he not receive a starting role on Monday.
The decision will test Mourinho's man-management.
