Bruno Fernandes and Odion Ighalo were Manchester United's only arrivals during the January transfer window, but more signings are expected during the summer.
Fernandes took over Ashley Young's number 18 jersey after the captain ditched the Manchester club for Italian side Inter Milan.
Ighalo, on the other hand, was handed the number 25 jersey, which initially belonged to yet another captain in Antonio Valencia.
A number of jerseys are still available for new signings, and with other players expected to leave the club, there are expected changes.
For now though, which shirt numbers are available?
The number is vacant following Alexis Sanchez's move to Inter Milan, and with his future at the club still unknown, it might be up for grabs by the time we start next season.
This was held by Anthony Martial until last summer when he ditched it for his favored number nine, which was held by Romelu Lukaku, who permanently moved to Inter Milan.
Chris Smalling, just like Lukaku and Sanchez, headed to Italy with AS Roma, and with the Italian side said to be keen on turning the loan move to a permanent move, the jersey might be vacant going into next season.
This shirt was vacated by Marcos Rojo, who completed a loan move to Estudiantes in January.
The shirt has never been worn since Marcus Rashford ditched it at the end of the 2017/18 season and remains vacant.
Marouane Fellaini left Manchester United at the end of the 2018/19 season, leaving the jersey number vacant.
Matteo Damian ended his stay at the Manchester club at the end of the 2016/17 season, and the shirt number is yet to get an owner.
