Barcelona midfielder Frenkie de Jong is set to miss a significant portion of the upcoming season after sustaining a tear to the medial collateral ligament (MCL) in his knee.

The Dutch international's injury is serious enough to keep him on the sidelines for several months, meaning he will not be available for the start of the new campaign.

The setback is a major blow for Barcelona, who will be without one of their key midfield figures for an extended period as they prepare for the season ahead.
