MADRID (Reuters) - Barcelona's 17-year-old midfielder Anso Vatti renewed his contract on Wednesday with the transfer of the penalty clause to 170 million euros ($ 188 million).

"The penalty clause in his contract will rise to 400 million when he signs a professional contract with the first team," a statement from Barcelona said.

Fati entered the history of the Catalan team earlier this season, after becoming the youngest player in Barcelona to score in the Spanish league, where he was then 16 years and 304 days.

Fati, who scored twice against Osasuna and Valencia, was given Spanish citizenship and was called up for Spain's under-21 team.

Fati's previous penalty clause was 100 million euros, although he was scored in the Barcelona squad. The new contract includes a substantial increase in his fee, according to Spanish press reports.

Fati has a contract with Barcelona that expires in 2022, with an option to extend the contract by two more years.
