When Rashford joined Barcelona on loan from Manchester United, the agreement between the two clubs was clear. Barcelona negotiated a purchase option worth €30 million that could be activated once the campaign ends. Importantly, the clubs also agreed on the financial framework of the player's potential contract, meaning there would be no need for fresh negotiations later.
The 28-year-old forward was ruled out of the semi-final first leg at the Riyadh Air Metropolitano due to knee discomfort after he picked up a knock in the game against RCD Mallorca. While the issue was not serious, Barça opted not to take any risks with the England international as a precautionary measure. Barcelona confirmed his absence for the trip to Madrid, but the decision is more a precaution than the result of a worrying injury.
When Barcelona sold him, the transfer fee was around €4 million. However, the club made sure to protect their long-term interests. They retained 40% of any future sale and also secured a right of first refusal, which could now become very important. Note that it is not a buy-back option, but it allows them to match any offer that Mallorca receive. For example, if a club bids €20 million for Virgili, Barcelona could match that amount and would have priority in negotiations.
