Celtic have announced the arrival of Lewis Morgan from St Mirren on a four-and-a-half-year contract.
Morgan, 21, has scored nine times in 20 Scottish Championship appearances during the 2017-18 campaign.
The attacker will remain on loan with St Mirren for the rest of the season before linking up with Celtic in the summer.
"Celtic are today delighted to announce the signing of highly-rated Scotland Under-21 internationalist Lewis Morgan from St Mirren on a four-and-a-half-year deal," read a statement from the Scottish giants.
"The 21-year-old has been in fantastic form for Jack Ross' side during the current campaign, scoring 13 goals to help them to the top of the Championship table, and he has attracted interest from a number of clubs."
Morgan has become Celtic's second January signing following the arrival of Marvin Compper from RB Leipzig.
