Carvalhal was sacked by Sheffield Wednesday a few days before he was appointed by Swansea.
However, Swansea's form has nosedived in recent weeks and a run of eight games without a win has left them facing nearly certain relegation.
Huddersfield needed a point to move out of reach of Swansea City - and achieved that despite Marcos Alonso canceling out Laurent Depoitre's opener.
"It would be wrong to raise the question (of a new deal) before the end of the season". If we still believe then we can stay (in the Premier League), we must do our part on the weekend and win the game.
"He is experienced, he is clever", Carvalhal said.

However, Roberts believes that Carvalhal has not been helped by the calibre of the squad at his disposal.
"No team is "too good to go down" and Mark Hughes seems to have reminded everyone of that, and I can only hope the team and the players have that in mind on Sunday and going into next season".
