Hinkel, who will make his debut against Stirling in the Scottish Cup on Saturday, told the Sunday Mail: "The next few months are vital because I want to make the Euro 2008 squad.

"It is one of my dreams to play at this tournament. Celtic are capable of winning the title and that would also give me tremendous joy.

"This season was bad for me at Sevilla. I need to play and believe that's possible in Scotland.

"I'll fight for my place from the moment I get there."

Dortmund were also interested in Hinkel but the 25-year-old was made to feel more wanted by the Hoops.

He said: "The Celtic directors influenced my decision. They fought for me and it was important to know they had confidence in my ability.

"It will be a challenge. Celtic have a history as one of the best clubs in Europe and Glasgow also has a great football tradition."
