The former Arsenal captain, who completed his move back to his boyhood side last week, was named in a strong starting XI for the annual Gamper Trophy exhibition match.

And, on his full debut following last week's substitute appearance in the Spanish Super Cup, the midfielder ingratiated himself to the Nou Camp crowd by opening the scoring in the 25th minute.

Midfield colleague Seydou Keita made it 2-0 before Lionel Messi replaced Fabregas and helped himself to a 15-minute hat-trick.
