Athletic Bilbao have signed midfielder Ander Herrera on loan from Paris Saint Germain for the 2022-23 season, the two clubs said on Saturday.

The deal includes an option to extend the loan for a second season or make the Spaniard’s transfer permanent, Bilbao said.

The 33-year-old returns to his old club, where between 2011 and 2014 he made almost 130 appearances in all competitions for the Basque team.

In his first season, he helped Bilbao reach the Copa del Rey and Europa League finals, losing 3-0 to Atlético Madrid.

“Coming back is a great joy (…) The challenges and demands are great,” Herrera said on the club’s Twitter (NYSE: TWTR ).

Herrera left Bilbao for Manchester United before the 2014-15 season and for five years in England he lifted the FA Cup, League Cup and Europa League trophies.
