Celtic have completed the signing of Greece international goalkeeper Vasilis Barkas.
The 26-year-old has agreed a four-year contract after making the switch from AEK Athens.
The deal is believed to have cost Celtic more than £4m.
Barkas, who was part of the Athens side that defeated Celtic in a Champions League qualifier in 2018/19, said he had signed to win trophies.
Speaking to Celtic TV, he said: “It’s a dream to come to one of the biggest teams in Europe, and I can’t wait to play for Celtic.
“Winning medals and trophies is why I came here. I want to win ten-in-a-row, and I want to help us get into the Champions League.”
