Former Arsenal star Ljungberg is poised to join the Scottish giants as Celtic boss Neil Lennon seeks new recruits as Cha and international compatriot Ki Sung-Yueng miss a month of club duty to play in January’s Asian Cup in Qatar.
“Freddie Ljungberg is a very famous player – and I like his underwear,” Cha told the Scottish Daily Record.
“I have a lot of Calvin Klein underwear at home – maybe I’ll show him. Seriously, he’s a good player and if he comes to us I think he can help us. It’s great.”
Both Cha and Ki were on the scoresheet in Celtic’s 2-0 win over St Johnstone on Sunday.
