Manchester United have approached Liverpool to register their interest for Pepe Reina. The Daily Star says Barcelona are favourites to re-sign the 30-year-old, who started his career at the Nou Camp, if he quits Anfield.

But sources in Spain claim United are also looking at him - and have made their interest known to Liverpool.

Reina looks set to leave Anfield at the end of the season, and Liverpool rate him at around £15m. They would be reluctant to sell to their bitter rivals, making Barcelona a more attractive option.
