Man United Squad Numbers for Schweni, Darmian & Schneiderlin

Manchester United completed three signings in the past few days by luring a defender Darmian and two midfielders in the form of Schweinsteiger and Schneiderlin.
The first summer signing Memphis Depay has not got an official shirt number as yet but Mirror revealed that the Dutch international might be wearing Number 26.
Shirt 26 was worn last by Japanese International Shinji Kagawa who never got a fair chance at Old Trafford. Depay will surely get his chance under Louis van Gaal though.
As far as the new trio is concerned, the German national team captain Bastian Schweinsteiger wore Number 31 shirt with Bayern Munich while he wears Number 7 with the four time World Champions.
Both numbers are occupied at Man United as Fellaini wears 31 and record signing Di Maria owns 7.
Morgan Schneiderlin wore Number 4 for Southampton and in the few appearances he has got for France, the versatile midfielder has been seen wearing Number 22.
Again, both numbers are not vacant at United with Jones and Powell covering the spots.
Defender signing from Torino, Matteo Darmian wears Number 4 with the national side and used to wear Number 36 with the Serie A side.
No one owns number 36 at Man United and the 24 year old full back may get that number.
The key vacant numbers at Manchester United are 9, 15, 19, 23-24, 26-29, 34, 36-40. What numbers should Man United new signings get? Have your say.
