Celtic: Ajax winger Derk Boerrigter joins on a four-year deal
Celtic have confirmed the signing of Ajax winger Derk Boerrigter ahead of Tuesday's Champions League transfer deadline.
Boerrigter, who could now feature against Elfsborg on Wednesday, has signed a four-year deal in Glasgow in what is expected to be a £3m move.
The 26-year-old was in his second spell at Ajax having re-signed in 2011.
He scored six goals last season and helped the club win their 32nd Eredivisie league title.
Boerrigter has also enjoyed spells with other Dutch sides Zwolle and RKC Waalwijk.
"He is the type of player we have been looking for for a while," said Celtic manager Neil Lennon, who is confident of another new signing this week.
"He is a very fast, direct, left-footed player who has goals in him with his left and right foot.
"He is also very powerful. He has good experience and he has played at a high level for the last two or three years."
Celtic face Elfsborg in Glasgow in their third round qualifier on Wednesday night, but had until midnight on Tuesday to add a "wildcard" signing eligible to play in the match at Celtic Park.
