During his time at Celtic, the Netherlands international established himself as (arguably) the best centre-back in the Scottish Premiership.
Bitton, who has been on the books of the Bhoys since 2013, understands why the Glasgow giants had to sell Van Dijk in the summer of 2015.
“Look at us last year - we had Jason Denayer and Virgil van Dijk and John Guidetti and others,” the Israel international told The Scottish Sun.”It is not about them, it’s about Celtic as a team. But I’m sure that if you play with the same 11 you see progress.
“People just think it is easy to keep these kind of guys. Look at Virgil - he has done so well in the Premier League. This is the way Celtic do it and it is not my job to say anything about it. I am happy and we need to make sure we build something together now.”
“If you have an offer for someone like Virgil - and the offer is good enough - then you need to sell the guy because it is his career and it is good money for the club,” added Bitton.
Van Dijk has done quite well at Southampton and has established himself as an important player for Ronald Koeman’s team.
The Dutchman has scored two goals and created six chances in 21 Premier League appearances for the Saints so far this season.
The former Groningen man has a pass accuracy of 83% and a shot accuracy of 43%, and has won 93 headers, 12 dribbles and 29 tackles.
