UEFA will consider introducing cheaper tickets for families attending Champions League finals in the future.
Michel Platini, the European governing body's president, has apologised for the high cost of final tickets at Wembley for next month's final, saying it was "a mistake". The cheapest tickets on general sale for the match on May 28 cost £150 plus a £26 administration fee, and the cheapest package for one adult and one child is only available in category two seats costing £338.
Platini, in London for the handover of the Champions League trophy, said: "It was a mistake, it was not good. But it is not easy to decide the price of the tickets in the Champions League final."
He added: "We have received 200,000 requests for 10,000 tickets and now on the black market these tickets are 10 times the price that we decided.
"Perhaps in the future we have to have another category for families that is less expensive. But if you put those on the black market how much will they cost?
"It was not a good communication and I apologise about that."
The remaining semi-finalists in the competition include Manchester United, who won their first European Cup at Wembley in 1968, and who have to get past Schalke to make it to the final.
Spanish opposition lie in wait with Barcelona facing Real Madrid in the other semi-final.
Football Association chairman David Bernstein, who was also at the Guildhall for the handover ceremony, said it would be "very special" for United to make it to the final.
Bernstein, a boyhood Manchester City fan, said: "We are very hopeful that Manchester United continue to progress and represent England. Club football in this country continues to be as strong as ever and five of the last six finals have involved an English side."
