Barcelona has the option to make the move permanent next summer for a reported fee of €30 million. The Spanish champions will also cover Rashford's wages for the duration of the loan, with the player reportedly taking a 25% pay cut to join the team.
Rashford has long been interested in playing for Barcelona, and this is his second consecutive loan spell. Last season, he spent the second half on loan at Aston Villa after his role at United decreased under Ruben Amorim.
A move away from Old Trafford seemed likely this summer, given that his number 10 shirt was handed to new signing Matheus Cunha. However, Barcelona is currently unable to register Rashford to compete in LaLiga due to financial rules.
LaLiga's financial regulations state that clubs can only spend as much as they earn. As a result, Barcelona must find alternative revenue streams or make player sales to accommodate their new signings.
Rashford is able to train and play in non-competitive games despite the registration issue. The team is working to resolve the financial constraints and register all players for the upcoming season.
