Celtic defender Virgil van Dijk has been tipped to make a move to the Premier League this summer amid interest from Arsenal, reports the Daily Star.
Rangers legend Arthur Numan has insisted that the 23-year-old has proved that he's too good for Scottish football and now needs to test himself in England's elite division.
Numan has also insisted that Van Dijk must be struggling for motivation at Celtic, with the player having to play the likes of Ross County 'seven times a season'.
Speaking to the Daily Record, he said: “If he gets the chance Virgil should go to England in January or at the end of the season. Over the last two seasons he has proved he is too good for Scottish football.
“If you are linked with some clubs in England it’s natural you are going to want to move away because you have Celtic in the top league here and who else?
“When a player comes to Scotland you spend a year or two trying to impress.
“But when you’re there four years and play Ross County seven times a season it can be hard to motivate yourself. You can stay too long.
Van Gaal snub
The former Rangers star has also suggested that new Manchester United boss Louis van Gaal left the centre-half out of his World Cup squad for the Netherlands this past summer because the player isn't proving himself against top strikers.
“Maybe Virgil will think now he needs another step in his career. Going to England to play in one of the best clubs in Europe may be better for himself and for the national team.
“If the Dutch coach comes over to see him play against Ross County he will wonder how Virgil would do against top international players. It’s hard to judge him when he is playing against strikers from a smaller team.
“I think that was the reason he was never in Louis van Gaal’s squad for the World Cup. He plays in Scotland while the other Dutch players are in big competitions and that is probably why he was never chosen.
“So in many ways he still has to prove himself. I always felt he was using Scotland as a stepping stone.
“But he is good enough to play in England right now. However, Virgil has to stay focused with Celtic to make sure clubs in England show interest."
It appears, then, that Gunners boss Arsene Wenger could make a move for the Celtic ace in the January transfer window, but it remains to be seen as to whether the Scottish champions will let him leave the club.
Arsenal appear to be in the market for another defender, despite signing youngster Calum Chambers from Southampton in the summer window. Ex-club captain Thomas Vermaelen left the club for Barcelona, meaning Chambers is the only real back-up for Per Mertesacker and Laurent Koscielny.
The Gunners' back-line will currently be preparing for the likes of Sergio Aguero and Co. as Manchester City travel to north London for a crunch Premier League clash this weekend.
Arsenal will be hoping to secure the three points against the Premier League champions, as they look to mount a serious title challenge this term.
