Slavisa Jokanovic is keeping calm about the prospect of facing at least one unhappy goalkeeper come the January transfer window.
Due to the latter's injury, Jesse Joronen was used in the EFL Cup and he will also have eyes on a first-team role.
With both Button and Bettinelli eyeing the number one jersey there is a belief, including from former Whites loanee Richard Lee, that the selection issue will come to a head at some point.
Jokanovic said: “I am not thinking in this way. All of my players have a chance to play in the starting XI.
“They don't need to look at a solution in another side. Tomorrow is training and a new chance to be stronger.
“They need to push hard. They don't need to look at another side for a solution. The solution is here at Fulham and is in their hands.
“They need to push hard to change the solution. We need to compete between us in the week and at the end of the week, against a different team.
“They don't need to think about January or June; they need to think about turning up at the training ground and what is in front of them.
“They need to find the way to support, help Fulham and their team-mates to be better and more competitive.”
