Palermo defender Ezequiel Munoz's hopes of moving to England could be scuppered by an agents row.

The Daily Mail says Sunderland and Swansea City are among clubs chasing Munoz but there is a wrangle developing over who represents him.

The 24-year-old Argentine is available for around £4m and has several European clubs on his trail with several agents also proposing a deal.

However, it is understood Italian agent Claudio Mossio is the man with the valid paperwork.
