Rashford missed training on Tuesday after picking up a knock in the win over Brighton but will travel with his team-mates to Spain. It remains to be seen if he can start.
“I can’t disclose my team, we’re not going to do that,” Solskjaer told reporters on Wednesday. “Marcus is travelling and we have to make a decision tomorrow if he starts or is on the bench. I don’t think he’ll play 90 minutes.”
Goalkeeper Dean Henderson, who started in place of David de Gea for a seventh straight game against Brighton, is in contention to don the gloves against Granada and Solskjaer said he had to make a choice between the two on a game-by-game basis.
“I cannot prioritise the league or Europa League. The next game is the most important one,” he said. “David has been a top keeper and is still a top keeper. I’m comfortable playing David or Dean and pleased that either of them are happy to be a sub.”
Solskjaer also said Anthony Martial had begun his recovery after sustaining a knee injury on international duty, but is unlikely to feature over the rest of the season.
“If we see him before end of season I’ll be very surprised,” he said. “He wants to get back as quick as possible.”
