Barcelona concerned by Manchester United's pursuit of Chelsea star

Spanish champions Barcelona are reportedly growing concerned that Manchester United may hijack their attempt to sign Willian from Chelsea.

The Brazil international has been strongly linked with a move to the Catalan giants after being restricted of regular gametime at Stamford Bridge for the second season on the bounce.

According to The Mail, the Blaugrana have already failed with multiple bids for the attacker and they are now worried that United could jump ahead of them in the player's pursuit.

Jose Mourinho's side have yet to make an approach to sign the 29-year-old but they could make a late raid for the attacker with the manager said to be concerned about the options on the right wing.

Willian has been with the Blues for the past five seasons where he has contributed 44 goals in 236 appearances. He was named the club's Player's Player of the Year last term.
