Lewis Holtby believes Tottenham Hotspur are capable of competing on four fronts this season and has predicted that the north London club are in with "a big chance of winning something".

Spurs have won eight of their opening nine matches in all competitions and Holtby believes that another victory, against Chelsea at White Hart Lane on Saturday, would give André Villas-Boas's squad such an injection of confidence that it would carry them through the remainder of the campaign.

Tuesday night's 4-0 thrashing of Aston Villa in the League Cup highlighted the strength in depth within a squad that has racked up 20 goals and conceded only once this season. Holtby has yet to start a Premier League game for Spurs this term but the German, who set up three goals in an impressive individual performance at Villa Park and also had a hand in Paulinho's winner at Cardiff on Sunday, is enjoying the challenge of forcing his way into a team that he expects to be a major force.

"Silverware is silverware. There's four cups to play for and you want to win all of them," Holtby said. "If you want to go to the top as a professional footballer you try to win every game and you try to win every trophy. That's what we are trying to do and we just have to work like we have as a team the last couple of weeks. We have a big chance of winning something but it is a very long season."

Asked whether it was important to beat Chelsea to prove to themselves, and not only the rest of the country, that Spurs can be authentic title contenders, Holtby replied: "Absolutely, especially for ourselves. I don't want to put that word [title] in the mouth but we are aiming for very high things. We want to get in the top four, we want to play Champions League. That is the main aim. I think we have the squad to do that, the quality and depth as well.

"It's early in the season. Unfortunately we lost the derby [against Arsenal 1-0] but we did the job in winning against the teams beneath us. We have to keep that up. Especially against Chelsea in the London derby, it is very important to win a big game like that to stay up top and give us the confidence we need."

Although Holtby has been restricted to only 20 minutes of Premier League football so far this season and has the unenviable task of trying to displace Christian Eriksen, the 23-year-old insists that he has no regrets about leaving Schalke for Spurs. "I get on with Christian very well. Off the pitch we do a lot of things," said Holtby.

"I wanted to come here. I could have stayed at Schalke, I could have played there all the time. But I wanted this challenge and to fulfil my dream of playing in the Premier League for a top, top club. Tottenham is going places and I'm happy to be part of it. I'm 23, I'm still young, I'm learning and progressing. And if I keep that momentum up, which I am doing right now, then I will get my chance to play, for sure.

"I have to show when I get the opportunity that I can produce something. If I keep working hard and putting on pressure it is going to be a very tough decision [as to who the manager picks] but we have so many games. I just saw the other day that we have eight games in December, January coming up and a tough November.

"You have to be prepared and up for it. At Bayern Munich everyone just did their work, did their job last season – that's why they won every title. They are always patient, they all work for the team, and that's how I see it here. If you keep producing things like we have done in the last couple weeks, then we have big things to do."
