Swansea are in a good bit of form, despite suffering the odd defeat, and they want to end the season on a high.
And while some fans are thinking the FA Cup could be a potential trophy, Carvalhal wants to focus on the main mission: staying in the Premier League.
They did suffer a heavy defeat at Brighton last time out in the league – and Carvalhal wants that performance stamped out of the players' system.
"We know why we lost the last game – that result did not damage us at all," he added.
"The atmosphere in the squad would have been good for West Ham even if we had not had this game, but it is true that the faces of the players are different when you win compared to when you lose."
