Interview with Chief Executive Peter Lawwell.
The highly-rated Dutch Under-21 internationalist joined Celtic in the summer of 2013 on a four-year deal from FC Groningen where he had forged a reputation as one of the most promising defenders in the Eredevise.
A tall and commanding centre-back, he is comfortable on the ball but also relishes the physical contest.
On the books of Willem II as a youngster, he moved to Groningen as a teenager and was soon making inroads into the first-team. He became regularly involved during the 2011/12 campaign and his impressive performances earned him international recognition for his country's Under-21 side.
Continuing to excel for Groningen, he started attracting interest from bigger clubs and Celtic won the race for his signature in June 2013.
Van Dijk was a stylish performer for Celtic throughout the last campaign, while he also chipped in with a few goals, most notably a solo effort against St Johnstone at McDiarmid Park, which saw him gather the ball on the halfway line and waltz through the opposition before scoring.
