The pair have impressed for Arsenal and Southampton respectively.
Both clubs are conceding at a rate of one goal very game so far and share only the top-flight's fourth best defensive records.
As individuals, though, Keown reckons the pair are at the top of the league - and for Southampton that usually means only one outcome.
"Virgil van Dijk has impressed me recently," wrote the former Arsenal defender, when asked to name his preferred modern-day partner. "I liked to play with a big central defender. I was good in the air but not the biggest, so I liked having the comfort of a mobile but big player alongside me such as Sol Campbell. I like the look of Van Dijk - I'm sure he'll be snapped up soon."
Keown added: "If I could roll back the years it would mean a lot to have played with Laurent Koscielny. I would have really enjoyed playing with him - he's a thoroughbred. He plays on the left, I played on the right, so let's do it!"
Van Dijk arrived at St. Mary's from Celtic 16 months ago and impressed so much that he was handed a new six-year contract earlier this year.
Having continued his fine form into the new campaign, however, speculation has increased that the Dutchman could soon be prised away from the Saints.
Liverpool are the most recent club to be linked with Van Dijk's services, after fierce rivals Manchester United.
The pair have acquired several Southampton players between them over the past couple of campaigns, with Morgan Schneiderlin and Luke Shaw heading to Old Trafford, and Sadio Mane, Nathaniel Clyne, Dejan Lovren and Adam Lallana; Anfield.
