The former Manchester United full-back has been speaking after his move to the Bhoys was confirmed on Wednesday afternoon.
Ex-Manchester United youngster Saidy Janko has spoken his first words since joining Celtic - and he is delighted with how smoothly his move to the Scottish champions was conducted, according to the club's official website.
Indeed, the 19-year-old's Celtic switch was confirmed on Wednesday afternoon and there were no complications as the full-back joined from Manchester United.
Janko, meanwhile, watched on as the Bhoys beat Den Bosch 2-0 in a friendly.
Celtic's new signing told the club's official site: "The move went quite smoothly, there was no hassle or anything so it was okay and I’m happy that the medical is over and I’ve signed a four-year deal."
And, in terms of his targets, the former Manchester United man is aiming high.
Firstly, Janko wants to play in the Champions League with Celtic - Ronny Deila's men are due to take part in the qualifiers for the tournament soon.
The Swiss is also eyeing international football with his country. He believes both of his goals are accomplishable with the Hoops.
Janko explained: "I’m looking forward to teaming up with my new team-mates and to the new challenge. Obviously Celtic are a huge club and I just want to get playing.
"Hopefully I’ll get as many games and as many trophies with the club as possible. I want to play in the Champions League and play international football, because with Celtic that is possible."
Another Celtic summer signing, Dedryck Boyata, was in action for the Bhoys against Den Bosch and largely impressed. Boyata, signed from the other Manchester club (City), also expressed his desire to form a long-term partnership with fellow centre-back Virgil van Dijk.
