The Daily Star says it's emerged that scouts have been flown to England to keep a close watch on Wilshere.
The La Liga champions will make their first move in January and hope to complete the deal in the summer, according to sources in Spain.
Signing Wilshere is seen as a priority for the Spanish giants.
Barca top brass believe he is the best possible alternative to replace Xavi and Andres Iniesta.
While Xavi and Iniesta are ageing, Wilshere - at 21 - is seen to have his best days ahead of him.
