Spurs came up short under the arch against Chelsea on Saturday evening as Antonio Conte's men won 4-2 to consign their capital rivals to a seventh consecutive FA Cup semi-final defeat.
Mauricio Pochettino's side have also failed to beat Monaco, Bayer Leverkusen and Gent at their temporary home this term, with a 3-1 victory over CSKA Moscow their only success.
Such a mediocre set of results does not compare favourably with Tottenham's stellar form at White Hart Lane, where they have won 15 of 17 top-flight fixtures this season.
But Alderwerield is adamant playing at Wembley is not a problem for him and his teammates, saying: "The last three games like CSKA Moscow and with 10 men against Gent we played very well.
"Today [Saturday] we played very well. It's not an issue about playing at Wembley.
"This team will get there. If it's not now or it's not tomorrow it will be the day after. We're confident."
Spurs have made significant strides during Pochettino's tenure but are yet to secure the piece of silverware that would solidify their progress.
But, having told Standard Sport last week that he is "100 per cent" the current Spurs side will lift a trophy, Alderweireld's confidence has not been knocked by defeat to Chelsea.
"We really want it [first trophy under Pochettino] but sometimes you have to have a little bit of luck," the Belgian added. "Today it wasn't there.
"We have to work hard and eventually it will come. If we keep doing the same things we're doing now and keep developing ourselves we will get there."
