CELTIC are to on the verge of completing the £3.5 million signing of striker Patryk Klimala according to reports in Poland.

Reports claim the Parkhead club have agreed a fee with Jagiellonia Bialystok for Klimala and the player will undergo a medical today.

The reports suggest that, barring any last minute hitches, the 21-year-old will become the Scottish champions' first acquisition of the January transfer window.

Celtic manager Neil Lennon has only had one fully-fit striker for much of the 2019/20 campaign due to Vakoun Bayo and Leigh Griffiths being out and has been keen to bring in back-up for Odsonne Edouard this month.

Klimala started his career at Rapid Vienna as a teenager, but didn't make a first-team appearance for the Austrian club and moved to Jagiellonia three years ago.

He spent last season on loan at second-tier Wigry Suwalki and scored 13 goals in 27 appearances.

The 6ft centre forward, who has played for the Polish Under-19 and Under-20 teams in the past, is considered one of his country’s most exciting prospects and has attracted the attention of the treble treble winners.

Klimala, who made his European debut in a qualifier against Rio Ave at the start of last season, had been targeted by Copenhagen, who Celtic play in a Europa League qualifier next month, in Denmark and clubs in Italy.

Asked about the clubs monitoring him last week, Klimala, who has scored seven goals in 17 matches this season, said that he was keen to move to a club where he would start in every game.

"From what I know, and I don’t know much, they were teams from Italy and Denmark," he said. "My manager is to call me only when there are specific offers on the table.

“I don’t know what will result, but the talks will definitely start in January. If someone wants me and it is a good option, I will go and fight.

“First of all, I don’t want to be the fourth choice, only the first. I want to develop, so I will also choose a league that will give me that.”
