Celtic have completed the signing of Jeremy Toljan on loan from Borussia Dortmund until the end of the season.

Toljan joined Dortmund from Hoffenheim in 2017 but has fallen out of favour under manager Lucien Favre so far this term.

The 24-year-old will now spend the remainder of the 2018-19 campaign on loan with Celtic, who currently sit six points clear at the top of the Scottish Premiership table.

"This is an exciting move for me and I'm delighted to be joining a club like Celtic, which has a great reputation throughout Europe," Toljan told the club's official website.

"I'm looking forward to meeting my new teammates and working with the manager, and I'll be doing everything I can to help the team to be successful in the remainder of this season."

Toljan becomes Celtic's second signing of deadline day after the arrival of Maryan Shved from Karpaty Lviv.
