Mauricio Pochettino says Tottenham will feel like a big club once they move into new stadium

Mauricio Pochettino has said Tottenham are a massive club but he believes they will struggle to win a trophy until they start to feel like one – which he hopes will happen when they move into their new stadium.

Pochettino is 'very confident' Spurs' new 62,062-seat home will be finished before Christmas following conversations with his chairman Daniel Levy and, not for the first time, the manager said the stadium could be the catalyst to win a first trophy since 2008.

Although he has previously admitted the move 'is not suddenly going to change everything and millions of pounds will rain from the sky', Pochettino believes Spurs' new home can lead to a mentality shift among his players, who have twice fallen short in the title race and lost consecutive FA Cup semi-finals since he joined the club in 2014.

Spurs will play at least the next two home league games and all three Champions League group-stage matches at Wembley, and they host Watford in Milton Keynes in tonight's Carabao Cup third-round.

Pochettino, who was reminded of the club's size en route to the Royal Festival Hall for Fifa's The Best Awards on Monday, says there will be no more excuses not to win trophies once they are in their new home.

"When I was going to the Best [Awards], it was unbelievable. The driver said, "I am a Tottenham fan!" Pochettino said. "This club is a massive. We only need to believe, trust in ourselves and feel that we are a big club. And of course, that belief will be massive when we finish the new stadium.

"Everyone is going to realise Tottenham is a massive club. We have an unbelievable, a big fanbase behind us. We need to feel that we're big. Until we feel that, it's difficult to win trophies. And that's why I think the stadium will be a big boost for everyone to try to believe now we can add trophies to our cabinet.

"I think you need to feel you're big and I'm sure the new stadium is going to help us. We're in a massive club but for everyone it will be a fantastic boost to say 'come on, we have amazing facilities, maybe the best in Europe or the world and now we need to win.' Not like winning now but no more excuses not to win [trophies]!"

Pochettino has said he will make five or six changes to his team for the match at Stadium MK after Spurs ended the worst run of his tenure – three straight 2-1 defeats – with victory by the same scoreline at Brighton on Saturday.

The Argentinian admitted he was frustrated by the criticism during the losing streak and preferred to focus on the bigger picture of his success and the club's potential ahead of tonight's game against the Hornets.

"Sometimes when you lose some games, it's like the past doesn't exist," he said. "It's so difficult but that is football. You need to accept that.

"But I'm so proud when I look back at the past and all that we have achieved, and I see how the club has changed. And the potential in the future to achieve all that the club deserves and the fans deserve because I think it's unbelievable."
