Supporters could be forced to pay as much as £133 for a ticket for the round-of-16 tie in Spain in February.

United have confirmed they have received an allocation of 2,450 tickets priced between £89 and £133 for the game at the Ramon Sanchez Pizjuan Stadium on Feb. 21.

It is an increase of 40 percent on the £54 Liverpool fans paid for a ticket when they played Sevilla in the group stages in November.

Sources have told ESPN FC United are aware of the issue while the Manchester United Supporters Trust say they are planning to take their case to UEFA.

A statement from MUST read: "It is too early to know whether we can change this but we are already in contact with both Manchester United and Football Supporters Europe (FSE) and will be lobbying UEFA and other bodies who may be able to influence this exploitative pricing."

United fans applying for tickets were initially told they would cost £54 -- an estimated cost set by United.

It is likely to mean some supporters will have to hand their tickets back if they are successful in the ballot.
