Celtic have completed the signing of Denmark striker Morten Rasmussen.
The 24-year-old frontman has joined the Hoops on a three-and-a-half-year contract from Brondby.
Rasmussen is believed to have cost Celtic a fee in the region of £1.5million.
Defensive duo Jos Hooiveld and Thomas Rogne have already arrived at Parkhead during the transfer window.
Speaking earlier in the month, boss Tony Mowbray admitted he was hoping to make significant changes to his squad this month.
"I am in the market for quality footballers," he said. "The board are fully aware of the situation.
"There are a lot of conversations going on at the moment with various clubs, either to sell players or to buy players."
