The Welsh international full-back is hoping to catch Chris Coleman's eye.
He has joined up with Championship side Bristol City and will help them in their fight against relegation from the Championship.
The right-back only arrived at Sunderland from Celtic in the summer but he has struggled to win around Sam Allardyce since returning from an ankle injury - and has featured for Sunderland just two times since the move.
Speaking about his loan departure he has admitted that his lingering hopes for Euro 2016 were a key factor in the move.
Matthews is quoted by The Sun as stating:
"It would be great if I can go to the Euros. I just want to get playing football again.
"Hopefully if I can start playing and playing well then I can turn heads in the Wales camp and get into the squad.
"I'm happy to sign, hopefully I can play football and if I go to the Euros that would be brilliant."
It would seem an uphill task. He has 12 caps for Wales but his injury problems have seen him not play for his nation since 2013.
He also has the likes of Chris Gunter, Jazz Richards and Adam Henley ahead of him in Chris Coleman's pecking order as Wales prepare for a momentous trip to France in the summer.
But if Matthews can thrive in his spell away from Sunderland then perhaps he can sneak his way back into contention.
