The news has cast doubt over Halilovic’s future, after Barca agreed a deal with Dinamo Zagreb last month to bring in the Croatian teenager this summer.
Reports on Thursday suggested that Manchester City and Manchester United were among a host of high-profile clubs to have been put on alert by the possibility availability of a 17-year-old dubbed the ‘new Lionel Messi’ in some quarters.

“The contract is signed and you can be sure that nothing unusual will happen.”
