Ahead of the new Premier League season, official kit numbers are slowly rolling in.
That includes Manchester United who - alongside Leicester City - will get the new season underway on Friday night at Old Trafford, ending the long wait for football fans across the country.
Fans have been tracking the squad numbers of their new signings with Fred most notably collecting the number 17 jersey, while Lee Grant and Diogo Dalot nabbed No.13 and No.20 respectively.
However, one of the most interesting developments has revolved around Marcos Rojo.
The Argentine is now entering his fifth season at United and has taken to the field with the number 5 on his back ever since Louis van Gaal signed him.
Rojo vacates No.5 jersey
That's about to change, though, as Rojo was revealed to have dropped the No.5 shirt in favour of the No.16 version that was vacated by Michael Carrick upon his retirement.
It wouldn't be the obvious decision in the eyes of supporters, but he's gone for it anyway.
And the move started speculation in the media and amongst fans that perhaps the club were making way for a potential January transfer for their defence.
Rio Ferdinand reacts on Twitter
After all, Jose Mourinho had been chasing centre-backs such as Toby Alderweireld and Diego Godin all the way to the deadline; could they be United's No.5 come winter?
Well, the situation has fans excited if nothing else and it caused so much reaction on social media that Rio Ferdinand himself couldn't help getting involved.
The United legend wore the No.5 shirt during his time at the club and, as a result, he couldn't resist jokingly suggesting his name as the man to claim it in January.
Take a look at his post below:
However, he did have a serious tweet to follow, stating that he wants a say in who the Red Devils eventually sign at centre-back. Check it out here:
And there was even time for a witty response from Gary Lineker:
Sorry Rio, but it's difficult to see United giving you the call, even if they struggled to sign a multitude of defenders in the summer market.
It can only be assumed that Mourinho will give it another shot when January rolls around and especially if United have fallen behind in the title race.
Since finishing second last season, there is less expectation around the team and arch rivals Manchester City and Liverpool are emerged as the main contenders.
There is great pessimism surrounding Old Trafford at the moment and even a new centre-back signing wouldn't necessarily have lightened the mood.
Only time will tell whether Ferdinand gets the consultation he desires.
