Virgil van Dijk says he learned more in five games at Southampton than he did during two years at Celtic.
The Dutch defender completed a £13m switch to the Saints in the summer and has started impressively, helping the Premier League side to four wins and a draw.
The 24-year-old is on the cusp of his first cap for Netherlands with Oranje set to play Czech Republic and Kazakhstan to determine whether they make the play-offs for Euro 2016.
And Van Dijk believes he can already feel the difference playing in the Premier League
“At Southampton I am learning so much in every game I play, much more than I did in two years at Celtic,” he told Dutch media outlet NU Sport.
“I feel I have started quite well. I’ve played five games and it has been tough. The standard is much quicker than in Scotland.
“The ball is like a pinball machine. You have to concentrate. It took me some time to get used to it but I’m doing all right now.”
