Barcelona are concerned about being gazumped by Manchester United in the race for Chelsea midfielder Willian.

The Daily Mail says the Blaugrana are fearful the Red Devils could yet usurp them in the race to sign the Blues flier.

Willian looks likely to leave Stamford Bridge following the arrival of Maurizio Sarri after Chelsea failed to finish in the top four last term.

Barca reportedly upped their offer to £65million on Saturday and are determined to lure the Brazilian to the Nou Camp.

However, United boss Jose Mourinho's connection to Willian could yet see Barca miss out on his signature.
