Celtic new boy Jack Hendry could be one half of a fine partnership.
Celtic secured a late deal for Dundee's Jack Hendry on deadline day and the defender's addition appears to be a real coup.
Hendry will have to compete for a spot in the short-term, but in the long term he is expected to become a regular for the Bhoys.
And alongside the emerging Kristoffer Ajer, Celtic may have their defensive partnership for the next decade.
Ajer is just 19-years-old and Hendry is 22. Between them they can establish themselves for years to come as the cornerstone of Celtic's success, domestically and in Europe.
Current option Dedryck Boyata does not look like the answer, while new boy Marvin Compper looks like a stop gap, useful in the short term but unlikely to be at the club in three years let alone five.
Ajer was signed by former boss Ronny Deila and spent last season on loan at Kilmarnock.
This campaign he has broken into the team and in recent weeks looked like one of Celtic's top players.
In the short term Brendan Rodgers may choose to play just one of the inexperienced Ajer and Hendry rather than select them together, but where he feels able to, he should put them in alongside each other and allow their potential partnership to begin to blossom.
