A free transfer has led to the signing of Albania's goalkeeper, Thomas Strakosha.
He left Lazio at the end of last season, after his contract expired.
Since joining the youth set-up, he's made over 200 senior appearances for the Italian side.
Thomas Frank said he was pleased that they had signed a top goalie.
He has been the number one at Lazio for a while. He has played in Italy and Europe and will bring that experience with him.
He made his senior debut in March of last year and has 19 caps to his name.
He will join Frank's squad on a pre-season training camp in Germany in the coming days.
He fits perfectly with the kind of goalkeeper we want here. He can play from the back and give us a lot of options.
The 18-year-old Yarmoliuk was signed by the Bees on a three year deal.
