Celtic new boy Patryk Klimala has vowed to score goals and “bring happiness” after joining the Parkhead club.
The Poland under-21 striker joined the champions on Tuesday from Ekstraklasa side Jagiellonia Bialystok.
He penned a four-and-a-half year deal for a reported fee of £3.5m.
Klimala has scored seven in 17 league appearances this season and has promised to add to that tally in Glasgow.
Speaking through an interpreter at Celtic Park, he said: “It is my biggest achievement so far and I am delighted to finally sign a contract with such a big team.
“Celtic fans are going to see a player who has come here to score a lot of goals.
“That is what I am planning to do and I want to bring a lot of happiness to them.
“Scottish football is slightly different to what I experienced in Poland.
“It is more aggressive but I am up for it and will do my best.
“I have come here to win a lot of trophies with the team and do my best, as I said before, to bring a lot of happiness. That is my main goal.”
Celtic’s first signing of the January window will provide competition to French striker Odsonne Edouard.
With a Scottish Cup tie away to Partick Thistle on Saturday on the horizon, the 21-year-old said: “I don’t expect to be in the first team after three days.
“I would love to be in the first team, however, I will do my best to fight for my place.
“At the end of the day it is the coach’s decision.”
