The 24-year-old spent the second half of last season on loan at Norwich City. He turned out 15 times for the Canaries, scoring one goal in the process and featuring in all but three potential fixtures, and that due to a three-match suspension.
With just a year left in his contract at last season's Europa League finalists, it would be no surprise to see him sold now rather than leaving for free this time next year, and it seems Birmingham have stolen a march on their rivals in a bid to bring him back to the Championship.
Now it is claimed the left-back is one step away from the Ajax exit and Birmingham are eagerly awaiting his potential arrival.
The report does not suggest that a deal has been done, but it does appear the Blues are in the box seat, provided they can agree personal terms with Dijks.
Birmingham finished last season in 19th position and manager Harry Redknapp will now want to guide his side up the table and make a push for the play-off places.
Blues boss knows exactly what it takes to win promotion out of the second tier and players like Dijks could make all the difference if a deal can be secured in the coming days.
