The Mail on Sunday says Lampard is the owner of Andres Iniestaâ€™s Barca shirt, the one the Spaniard wore in the Champions League semi-final at Stamford Bridge last season in which Iniesta equalised in injury-time to knock out Chelsea.
That moment is still considered the most dramatic of Barcaâ€™s season, despite the fact they went on to win the Champions League, the Spanish league and cup.
Asked last week to produce the shirt, Iniesta said: "I donâ€™t have it - I gave it to Lampard. That moment was the happiest of my life. Naturally, I was crying, as were all the people there. It was overwhelming."
