Hamburg full-back Marcell Jansen believes his side have what it takes to win the Bundesliga this season following their victory over Bayer Leverkusen.
Jansen scored his first brace in the top flight to take Hamburg to the top of the table with a 2-1 win over Leverkusen.
They are now two points clear of Hoffenheim and Hertha Berlin, and four above his former club Bayern Munich.
And Jansen told the Hamburger Abendblatt newspaper his team must be seen as serious title contenders.
"We have the compactness which you need to win the title," said the 23-year-old. "We are already as good as Bayern in this regard. We are strong at the back and dangerous in attack and that is what you need to win the title."
However, Jansen is refusing to get carried away with the situation in the tightest league in Europe at present.
Six teams are packed together within six points at the top, including their next opponents Wolfsburg, and Jansen knows how quickly things can change.
"This is just a momentary situation which we can be happy with for today and tomorrow, but then we have to move on," he said. "On Thursday we have the UEFA Cup and then on Sunday we are at home to Wolfsburg.
"It is very tight at the top, but if we can remain on track and not take off and think we have already achieved something, then we will have a successful season.
"Everybody is allowed to dream, but we players can only celebrate and enjoy the one evening.
"We have got to be realistic and above all think we still have a full programme ahead of us."
