Virgil van Dijk was at Celtic for two seasons.
Van Dijk joined Celtic from Groningen in the summer of 2013, and after two successful years at Celtic Park, he moved to Southampton in the Premier League in England.
Now on the books of Liverpool and valued at €120 million (£106.99m) by the CIES Football Observatory, the 28-year-old Netherlands international central defender has spoken highly of the Hoops.
The defender believes that Celtic are underestimated at times, and has raved about the fans of the Scottish Premiership giants.
The Daily Record quotes Van Dijk as saying: “Celtic are a massive club and people underestimate them sometimes. It’s such a historic club, a great environment to be (a part of).
“The fans are outstanding, the stadium is amazing and to get Champions League in my first season there was great for my development.”
Successful season
Celtic have won the Scottish Premiership title for the past eight seasons, and have clinched the domestic treble for the last three years.
The Celtic Park faithful will want the team to win all the domestic trophies this season as well, and progress to the knockout round of the Europa League.
The Hoops are currently behind bitter Old Firm rivals Rangers in the Scottish Premiership table, but they could well go back to the top of the league table soon.
