Celtic are reportedly closing in on Ajax winger Derk Boerrigter ahead of Tuesday's Champions League deadline.
The Hoops must sign the 26-year-old by midnight for him to be eligible to face Elfsborg in Wednesday's third-round qualifier at Parkhead.
The Dutchman is in Glasgow to finalise a £3m deal, according to BBC Sport.
Boerrigter scored six goals last season as Ajax claimed the Eredivisie title.
