Josip Juranovic has agreed personal terms with Celtic and is set to jet into Glasgow this week to complete his medical, according to reports in Poland.
The Hoops are understood to have had a £2.5 million bid for the Croatian international right back accepted by Legia Warsaw for a position Ange Postecoglou has been determined to strengthen.
And now multiple reports around the Ekstraklasa claim the the 26-year-old - a team-mate of ex-Celtic goalkeeper Artur Boruc at Legia - has agreed his own personal terms to give him the green light to make the move to Parkhead.
Legia Warsaw are set to take on Slavia Prague in the first leg of their UEFA Europa League play-off clash in the Czech Republic on Thursday.

Boss Czeslaw Michniewicz is expected to give an update on the situation at the pre-match press conference ahead of that game.
Juranovic is still expected to play in the match and is included in his side's UEFA squad list as it stands, before arriving in Glasgow for a medical ahead of Celtic’s clash with St Mirren this weekend.
He would, however, be ineligible for the Hoops' return Euro clash against AZ Alkmaar in Holland next week and that could mean a potential baptism of fire against Rangers at a packed Ibrox on August 29.
Postecoglou, when asked about Juranovic ahead of his side’s clash with AZ, said: "He'd be one of a number of right full-backs we have been linked over the period I have been here.
“It's obviously an area where we definitely need some cover. At the moment Anthony Ralston is doing an outstanding job and I think there's more in him to improve. But he can't play every game.”
