Ben Amos wants to help Charlton win promotion before sorting out his future.
Amos, 27, joined the Addicks on a season-long loan from Bolton in the summer.
The former Manchester United goalkeeper was frozen out by Trotters boss Phil Parkinson and loaned to Cardiff last term. He has two years left on his Bolton deal.
Amos has started every league game under Charlton chief Karl Robinson this season, keeping three clean sheets.
When asked if he is thinking about his future, Amos said: “I’m literally just giving Charlton my 100 per cent and a lot of football is out of [my] control. What happens, happens.
“I just want to do my best here and want to play football at the best level I can and at the best teams. So I’ll leave that to other guys to crack on with.
“I’m very much just giving this my all on the pitch, off the pitch for Charlton. What will be, will be, that’s certainly my philosophy. I’ll work as hard as I possibly can and see where it takes me.”

Amos ended the 2016/17 campaign as Cardiff manager Neil Warnock's third-choice goalkeeper.
He played just 12 times for Warnock after being pushed down the pecking order by Brian Murphy and Allan McGregor.
Recalling his difficult spell with the Welsh club, Amos added: “I’m old enough to know that’s football.
“I don't want to say some managers have their own agenda, but some things are out of your control.
“You can’t get too up or down - I think you’ve got to stay balanced and be consistent.
“It was fine [my relationship with Warnock] - that was last season. I don't want to get into that. I’m trying to stay in the present and look forward. I’m not concerned about that now.
“I just want to do the best I can for Charlton and get the best results I can.”
Charlton have made a strong start to the League One season and sit fifth with a game in hand.
They are eight points behind Wigan and Shrewsbury, who occupy the automatic promotion places.
Amos said: “The top two is the ultimate aim - we’ve got another tough game against Oxford on Tuesday.
“It’s all we can do, take each game as it comes, it’s a terrible cliche but it’s true.
“As soon as you start looking too far ahead, we’re only in October, there’s a lot of football to be played between now and Christmas. So consistency is the key to us.”
