Tottenham star Rafael van der Vaart says a lack of experience is costing Arsenal in the biggest games ahead of Wednesday night's crucial north London derby.
The 28 year-old Dutchman who moved to White Hart Lane in the summer from Real Madrid said he feels confident that Tottenham could complete a league double of its arch rivals.
"Arsenal have a young team," he told talkSPORT. "That's the problem with a young team - once, you play fantastic, but in the other games, maybe the most important games, you drop points.
"They still have a fantastic team. It will be an open game. But we showed at the Emirates a few months ago that we can beat them."
Van der Vaart, who was shortlisted for the PFA Player of the Year prize won by his team-mate Gareth Bale on Sunday evening, said Spurs were keen on returning to top level European football next season.
He added: "It's not going to be easy. We have to win all our games and this is one of the most difficult games of the year. But we want to play in the Champions League next year."
The attacking midfielder inspired his team to a memorable 3-2 win at the Emirates in November.
