Blackpool have made free agent Marc Bola their 11th signing of the summer.
The defender, who had been on trial with Wigan Athletic until recently, has agreed an initial one-year deal with the Seasiders, with the option of a further 12 months.
The 20-year-old was released by Arsenal last season having spent the campaign on loan at Bristol Rovers, making 23 appearances.
The previous season he made 13 appearances during a loan spell at Notts County.
“I’m delighted to join Blackpool and I just can’t wait to get started," Bola said.
"I’ve had great years at Arsenal and I’m looking forward to building a new chapter now.
"I kind of got used to the league when I was at Bristol Rovers on loan and I now just want to play more games and prove how good I am.”
While predominantly a left back, Bola is also capable of playing on the right-hand side of defence.
