2020/21 Manchester City Training Top (Player Worn?)

What looks like a player worn top of which only the player versions had the sponsor on them. City regained the title after an inconsistent first half of the league season and won their fourth successive Carabao Cup.
 
Top in a great condition. It has 31 on the neck (Ederson's squad number) and the sleeves have been cut at the cuffs (pictures 3 and 4).
