Rashford was left out of the starting lineup for Barcelona's recent match against Getafe after being late to a pre-match meeting.
Shearer believes that Rashford has the potential to be a valuable player, citing his impressive performance against Newcastle as an example.
However, Shearer also emphasized the importance of being on time and professional, stating that being late can negatively impact the team.
He noted that being on loan at a top club like Barcelona means that there are always other players who can take Rashford's place, making it crucial to maintain a good attitude and be punctual.
Shearer's comments suggest that Rashford's behavior may impact his chances of staying at Barcelona beyond his loan period.
