Alcaraz insists the only game that matters is Saturday's Premier League visit of Norwich.
"We have Wembley to look forward to, but for me the most important game is always the next one and that is Norwich City," Alcaraz told the Wigan Evening Post.
"We will worry about the FA Cup when it comes around next month. For now we must concentrate on the league because there are some important games coming up. We have shown in the last few games that we can win games in this league, and we must keep that up if we are to move away from the bottom of the table."
