Celtic have already launched transfer plans to replace Carl Starfelt, with the Swede expected to leave Parkhead this week.
The 28-year-old has been heavily linked with a move to La Liga side Celta Vigo in a deal worth £4.3miliion.
Brendan Rodgers confirmed after Saturday's Scottish Premiership win over Ross County that Starfelt had likely played his final game for the club and plans were in motion to bring in a replacement.
Reports in Sweden now suggest that Celtic are looking to bring in Elfsborg defender Gustaf Lagerbielke as a possible replacement in a £3million move.
The 23-year-old is viewed to have great potential and has already featured for his national team on one occasion.
Speaking after Saturday's win over Ross County, Rodgers explained about Starfelt saying: “I wanted to put Carl Starfelt on because it might be his last game here. He has been a great servant to the club. There is interest in him and he would like to take up that possibility. We will resolve that as quick as we can.
“The clubs are in communication so I am sure that will go through at some point early next week, if not before.
“He probably felt it was the time to move on. There are certain conditions there that has made him think he will be going to one of the top leagues, and economically it’s hard for us to compete on that side, and obviously his partner is no longer here and has moved on.
“But I have to say, total professional, first class and if it didn’t go through, I know I can rely on him, but I think it probably will.
“We would need to get another centre-half. My idea is to get four centre-halves who are competitive.”
