The napkin on which Barcelona committed to sign a 13-year-old Lionel Messi has been sold in an auction for £762,400.

The starting price was £300,000 for the ‘standard Spanish waxy napkin’ which is 16.5 x 16.5cm and was laminated and framed.

The napkin, signed in blue ink in December 2000, carries a pledge from then Barcelona director Carles Rexach to sign Messi.

It was also signed by Josep Minguella, a transfer adviser to the Spanish club, and agent Horacio Gaggioli, who recommended the Argentine youngster.

The napkin in blue ink was offered in an online auction by London-based Bonhams on behalf of Gaggioli.

Messi joined Barca a month after the deal was agreed and went on to become their record goalscorer and many regard him as the greatest player of all time.

He made his first-team debut aged 16 and scored a record 672 goals in 778 games for the Catalan club.

Messi won 10 La Liga titles and the Champions League four times at Barcelona before leaving for Paris St-Germain in 2021 – and the 36-year-old World Cup winner now plays for Inter Miami.

The napkin was signed at a meeting arranged by Rexach, who invited Messi’s father Jorge to lunch after concerns from the Messi family about a lack of response from Barcelona following the teenager’s initial trial.

Translated into English, it reads: “In Barcelona, on 14 December 2000 and in the presence of Messrs Minguella and Horacio, Carles Rexach, FC Barcelona’s sporting director, hereby agrees, under his responsibility and regardless of any dissenting opinions, to sign the player Lionel Messi, provided that we keep to the amounts agreed upon.”
