Manchester United midfielder Ander Herrera remains on the radar of Barcelona.

Sport says Herrera is viewed by Barca as an alternative to €100 million-rated PSG midfielder Marco Verratti.

The midfield schemer produced the best football of his career last season under United manager Jose Mourinho and has been tipped for the club captaincy next term.

However, United's resolve will be tested by Barca if PSG refuse to do business over Verratti next month.

Herrera's signing has been endorsed by new Barca coach Ernesto Valverde, who worked with the midfielder at Athletic Bilbao.
