Sergio Busquets has become uneasy with the slow progress of his contract talks, according to Sport.

Manchester City, Paris Saint-Germain and Manchester City are all interested in Busquets and are preparing offers.

If Jose Mourinho joins United, Busquets almost certainly would prefer to join Pep Guardiola at City.

PSG view Busquets as an ideal replacement for Thiago Motta.
