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.

4. 14 (Currently: Christian Eriksen)
United were open to selling Eriksen this summer, but he looks likely to stay at the club. If an exit materialises in the final two weeks then his shirt number could represent an attractive choice. | Manchester United via Getty Imag Photo: Manchester United via Getty Images
