"I don't think it's appropriate to comment on anything that happened before," he told the Daily Echo.

With just five points from their last six Premier League matches, van Dijk reckoned the international break has arrived at the right time for 13th placed Southampton.
He said it was an ideal pause to get their act together ahead of a demanding schedule until the end of the year, starting with a league trip to Liverpool on Nov. 18.
"Every game is important and it's going to be even more important now to get some points and we know we can play very well against everyone," van Dijk said.
"For now, we need to recharge with some of the players going back to their countries and work hard there as well and come back fit and be ready for Liverpool."
