The Argentina winger has signed with the Warriors subject to him obtaining a visa and passing a medical.

In a seven-year international career, Piossek has become the Pumas' all-time leading try scorer with 30 tries in as many appearances.

He played against some of his new team-mates when Argentina secured victory over Scotland in the first summer Test in Rosario.

Lineen said: “I’m delighted to have Jose on board. He’s an experienced international and definitely knows where the try line is.

“He is a pretty important signing in terms of the experience he’ll bring to the squad, he’s also very good value for money.

“He’s a tough player looking for rugby and will bring a bit of balance to the squad because we need to manage the game time of our Scotland internationals. I’m also looking for Jose to be a big influence on our young Scottish players such as Chris Kinloch, Ruaridh Jackson and Peter Horne who is aligned to Glasgow from the National Academy.”
