“Tymoteusz is someone we have been aware of and monitoring for a few months,” Argyle head of recruitment jimmy Dickinson told the club website.
“He comes to Argyle with an excellent record and varied experience from several big clubs throughout Europe.
“There was plenty of competition for his signature, but he is excited by the challenge ahead and felt Argyle was the best fit for the next stage of his career.
“He is naturally left-footed, good on the ball, and consistently provides assists, so will provide good balance to the left side of defence but also add further competition for places.”
