Manchester United are set to go Double Dutch in the summer transfer window with the additions of both Joshua Zirkzee and Matthijs de Ligt.
Erik ten Hag's side have already reached an agreement for Zirkzee to play for the club in the coming season, while talks are ongoing to strike an agreement with De Ligt.
The two new signings would be a huge boost to United's hopes heading into the campaign and would signal the strong pulling power of the club even without Champions League football.
Both players would be entitled to three weeks off following the conclusion of their respective European Championship campaign, meaning it might not be until next month that we get to see either of them in a United shirt.
However, we should know their new squad numbers long before that, and these are the numbers available to them this summer.
5. 18 (Currently: Casemiro)
You can't think of the No.18 shirt without envisaging Paul Scholes. It was also worn by Bruno Fernandes and Ashley Young and will be available this summer if United find a buyer for Casemiro. Perhaps the perfect next step in Kobbie Mainoo's club career. | Manchester United via Getty Images Photo: Manchester United via Getty Images
6. 19 (Currently: available)
It's not the most favourable number but is another that is now available. As worn by Danny Welbeck, Marcus Rashford and James Wilson, it is perhaps best saved for an emerging striker next. | Manchester United via Getty Images Photo: Manchester United via Getty Images
7. 21 (Currently: Antony)
Antony looks set to stay at United this summer so his shirt number is unlikely to become available. If he does end up leaving, it is another decent option for a youngster to upgrade to. | Manchester United via Getty Images Photo: Manchester United via Getty Images
8. 25 (Currently: Jadon Sancho)
United could sell Sancho before deadline day but his shirt isn't likely to have many takers. It was most famously worn by former captain Antonio Valencia. | Manchester United via Getty Images Photo: Manchester United via Getty Images
