Barcelona are demanding a public show of commitment from Manchester United target Cesc Fabregas.
The Daily Mail says United's pursuit of Fabregas could also come to a head this week.
Barcelona are understood to have told Fabregas to state publicly that he wants to stay at the Nou Camp, while the club's director of football Andoni Zubizarreta claimed last night that United now accept he will not be sold.
However, David Moyes's interest remains as strong as ever and the United boss is ready to make a third bid of £35m if he receives positive signals from Fabregas' representatives.
