Nicolas Kuhn has admitted he is thrilled to have finally signed for Celtic after a "stressful" transfer process and "problems" in departing Vienna.

The winger became Brendan Rodgers' first signing of the January window as he signed a five-and-a-half-year deal at Parkhead.

Kuhn, 24, did have other offers on the table this month but decided on a move to Glasgow with Celtic paying a transfer fee in the region of £3million.

But the former Germany youth international revealed it was a stressful journey to Celtic with "problems" in Vienna leading to a delay in finalising his switch.

In his first press conference as a Celtic player, Kuhn said: "It was a stressful week but I am really happy to be here. I have met all my team-mates and the staff and a lot of people around the club, really nice people.

"I can't wait to get started."

Quizzed on the stressful week, Kuhn explained: "When I was at Vienna still, there were some problems with coming here. It took a little bit longer than expected so I had to wait the whole time to take a flight here.

"Then it was getting really fast, I had to do the medical check and fly to Glasgow, then I had all the pictures in the evening. 

"Yesterday was my first time at the club and today was my first training session so there were a lot of things to do."

Kuhn - previously at Ajaz and Bayern Munich - is hopeful his switch to Celtic could help him achieve international ambitions and fulfil his desire to perform in the Champions League.

He added: "For me it was clear the moment Celtic called and showed interest that I wanted to come here.

"There was some interest from other clubs. But the moment I received the message, I didn't really think about going somewhere else.

"I want to play in the Champions League and go to the national team. Now I made a big step to a big club. Of course in the future I want to play for the national team, that was a point in why I came here.

"The opportunity is really nice. If you see the stadium and everything, and the fans, it is unbelievable."
