Barcelona are tracking Manchester United midfielder Ander Herrera.

The Daily Star Sunday says Herrera has been one of United's brighter players but he has often been placed on the fringes of the starting XI.

Barca are hamstrung by a transfer ban but they are weighing up who to bring in as replacements for the ageing Xavi and Andres Iniesta.

Xavi intends to stay another season at Barca despite offers from New York and the Middle East.
